4-bit dual supply translating transceiver; 3-state
Rev. 2 — 6 February 2020
Product data sheet
1. General description
The 74AXP4T245 is an 4-bit dual supply translating transceiver with 3-state outputs that enable
bidirectional level translation. The device can be used as two 2-bit transceivers or as a 4-bit
transceiver. It features four 2-bit input-output ports (nAn and nBn), a direction control input (nDIR),
a output enable input (nOE) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can
be supplied at any voltage between 0.9 V and 5.5 V making the device suitable for translating
between any of the low voltage nodes (0.9 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). No power
supply sequencing is required and output glitches during power supply transitions are prevented
using patented circuitry. As a result glitches will not appear on the outputs for supply transitions
during power-up/down between 20 mV/µs and 5.5 V/s.
Pins nAn, nOE and nDIR are referenced to VCC(A) and pins nBn are referenced to VCC(B). A HIGH
on nDIR allows transmission from nAn to nBn and a LOW on nDIR allows transmission from nBn to
nAn. The output enable input (nOE) can be used to disable the outputs so the buses are effectively
isolated.
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 nAn and nBn
are in the high-impedance OFF-state.

[1] CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC2 × fi × N + Σ(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;
Σ(CL × VCC2 × fo) = sum of the outputs.
[2] fi = 1 MHz; VI = GND to VCC; tr = tf = 1 ns; CL = 0 pF; RL = ∞ Ω.
