NTSX2102
Dual supply translating transceiver; open drain; auto
direction sensing
Rev. 2 — 11 February 2013
Product data sheet
1. General description
The NTSX2102 is a 2-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 2-bit input-output ports
(An and Bn), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). Both
supplies can be supplied at any voltage between 1.65 V and 5.5 V. This flexibility makes
the device suitable for translating between any of the voltage nodes (1.8 V, 2.5 V, 3.3 V
and 5.0 V). Pins An and OE are referenced to VCC(A) and pins Bn are referenced to VCC(B)
A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state. This
device is fully specified for partial power-down applications using IOFF. The IOFF circuitry
disables the output, preventing the damaging backflow current through the device when it
is powered down.
.
2. Features and benefits
Wide supply voltage range:
VCC(A): 1.65 V to 5.5 V and VCC(B): 1.65 V to 5.5 V
Maximum data rates:

14.2 Architecture
The architecture of the NTSX2102 is shown in Figure 9. The device does not require an
extra input signal to control the direction of data flow from A to B or B to A. The NTSX2102
is a "switch" type voltage translator, it employs two key circuits to enable voltage
translation:
1. Two pass-gate transistors (N-channel) that tie the ports together.
2. An output edge-rate accelerator that detects and accelerates rising and falling edges
on the I/O pins (see Figure 10).

During an input transition, a one-shot accelerates the output transition by switching on the
PMOS transistors (T1, T3) for a LOW-to-HIGH transition. Alternatively, it switches on the
NMOS transistors (T2, T4) for a HIGH-to-LOW transition. Once activated, the one-shot is
de-activated after approximately 25 ns (see Figure 11). During the acceleration time, the
driver output resistance is between approximately 10 and 35 . To avoid signal
contention, the application must not exceed the maximum data rate or wait for the
one-shot circuit to turn-off, before applying a signal in the opposite direction.

14.3 Input driver requirements
As the NTSX2102 is a switch type translator, properties of the input driver directly affect
the output signal. The external open-drain driver applied to an I/O, determines the static
current sinking capability of the system. The maximum data rate, output transition times
(tTHL, tTLH) and propagation delays (tPHL, tPLH) are dependent upon the output impedance
and edge-rate of the external driver.
14.4 Output load considerations
The maximum lumped capacitive load that can be driven is dependent upon the one-shot
pulse duration and has been tuned to 600 pF. In cases with higher capacitive loading,
there is a risk that the output does not reach the positive rail within the one-shot pulse
duration. To avoid excessive capacitive loading and to ensure correct triggering of the
one-shot, use short trace lengths and low capacitance connectors on NTSX2102 PCB
layouts. The length of the PCB trace should be such that the round-trip delay of any
reflection is within the one-shot pulse duration. Such a length ensures low impedance
termination and avoids output signal oscillations and one-shot retriggering.
14.5 Output enable (OE)
An output enable input (OE) is used to disable the device. Setting OE = LOW causes all
I/Os to assume the high-impedance OFF-state.
14.6 Power-up
When either of the supplies VCC(n) is at 0 V, outputs are in the high-impedance OFF-state.
One of the advantages of NTSX translators is that either VCC(A) or VCC(B) may be powered
up first. To reduce dissipation during power-up, ensure that output enable (OE) is defined.
Connect it via a pull down resistor to GND or, if the application allows, hardwired to VCC(A)
.
If the OE pin is hardwired to VCC(A), either supply can be powered up or down first. If a pull
down is used, the following sequences are recommended.
For power-up:
1. Apply power to either supply pin
2. Apply power to other supply pin
3. Enable the device by driving OE HIGH
For power down:
1. Disable the device by driving OE LOW
2. Remove power from either supply pin
3. Remove power from other supply pin
14.7 Pull-up resistors on I/O lines
Each A port I/O requires a pull-up resistor to VCC(A), and each B port I/O requires a pull-up
resistor to VCC(B). Choose the magnitude of the pull-up resistors to ensure that the output
voltage levels meet the application requirement.
