74LVC32245A
32-bit bus transceiver with direction pin; 5 V tolerant; 3-state
Rev. 2 — 8 November 2011
Product data sheet
1. General description
The 74LVC32245A is a 32-bit transceiver featuring non-inverting 3-state bus compatible
outputs in both send and receive directions. The device features four output enable (nOE)
inputs for easy cascading and four send/receive (nDIR) inputs for direction control.
Pin nOE controls the outputs so that the buses are effectively isolated.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs. These features allow the use of these devices in mixed
3.3 V and 5 V applications.
To ensure the high-impedance state during power-up or power-down, pin nOE should be
tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by
the current-sinking capability of the driver.
