Product data sheet
1. General description
The 74AVC32T245 is a 32-bit transceiver with bidirectional level voltage translation and
3-state outputs. The device can be used as eight 8-bit input-output ports (nAn and nBn),
two 16-bit transceiver or as a 32-bit transceiver. It has dual supplies (VCC(A) and VCC(B))
for voltage translation and four 8-bit input-output ports (nAn and nBn) each with its own
output enable (nOE) and send/receive (nDIR) input for direction control. VCC(A) and VCC(B)
can be independently supplied at any voltage between 0.8 V and 3.6 V making the device
suitable for low voltage translation between any of the following voltages: 0.8 V, 1.2 V,
1.5 V, 1.8 V, 2.5 V and 3.3 V. A HIGH on nDIR selects transmission from nAn to nBn while
a LOW on nDIR selects transmission from nBn to nAn. A HIGH on nOE causes the
outputs to assume a high-impedance OFF-state
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.
