74AVC4T245
4-bit dual supply translating transceiver with configurable
voltage translation; 3-state
Rev. 01 — 20 July 2009
Product data sheet
1. General description
The 74AVC4T245 is an 4-bit, dual supply transceiver that enables bidirectional level
translation. The device can be used as two 2-bit transceivers or as a 4-bit transceiver. It
features two data 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 0.8 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 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.
