Dual-bit, dual-supply voltage level translator/transceiver;
3-state
Rev. 7 — 8 February 2013
Product data sheet
1. General description
The 74AVC2T45 is a dual-bit, dual-supply transceiver that enables bidirectional level
translation. It features two data input-output ports (nA and nB), a direction control input
(DIR) and dual-supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at
any voltage between 0.8 V and 3.6 V making the device suitable for translating between
any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins nA and DIR
are referenced to VCC(A) and pins nB are referenced to VCC(B). A HIGH on DIR allows
transmission from nA to nB and a LOW on DIR allows transmission from nB to nA.
The device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing any damaging backflow current through the
device when it is powered down. In Suspend mode when either VCC(A) or VCC(B) are at
GND level, both A and B are in the high-impedance OFF-state.
2. Features and benefits
Wide supply voltage range:
VCC(A): 0.8 V to 3.6 V
VCC(B): 0.8 V to 3.6 V
High noise immunity

JESD8-11 (0.9 V to 1.65 V)
JESD8-7 (1.2 V to 1.95 V)
JESD8-5 (1.8 V to 2.7 V)
JESD8-B (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F Class 3B exceeds 8000 V
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101C exceeds 1000 V
Maximum data rates:
500 Mbit/s (1.8 V to 3.3 V translation)
320 Mbit/s (<1.8 V to 3.3 V translation)
320 Mbit/s (translate to 2.5 V or 1.8 V)
280 Mbit/s (translate to 1.5 V)

[1] CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + (CL VCC2 fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
(CL VCC2 fo) = sum of the outputs.
[2] fi = 10 MHz; VI = GND to VCC; tr = tf = 1 ns; CL = 0 pF; RL = .

13.2 Bidirectional logic level-shifting application
Figure 10 shows the 74AVC2T45 being used in a bidirectional logic level-shifting
application. Since the device does not have an output enable (OE) pin, the system
designer should take precautions to avoid bus contention between system-1 and
system-2 when changing directions.

13.4 Enable times
The enable times for the 74AVC2T45 are calculated from the following formulas:
• ten (DIR to nA) = tdis (DIR to nB) + tpd (nB to nA)
• ten (DIR to nB) = tdis (DIR to nA) + tpd (nA to nB)
In a bidirectional application, these enable times provide the maximum delay from the
time the DIR bit is switched until an output is expected. For example, if the 74AVC2T45
initially is transmitting from A to B, then the DIR bit is switched, the B port of the device
must be disabled before presenting it with an input. After the B port has been disabled, an
input signal applied to it appears on the corresponding A port after the specified
propagation delay.
