74ACT16245 16-Bit Transceiver with 3-STATE Outputs

August 1999 Revised May 2005

74ACT16245 16-Bit Transceiver with 3-STATE Outputs
General Description
The ACT16245 contains sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each has separate control inputs which can be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state.

Features
s Bidirectional non-inverting buffers s Separate control logic for each byte s 16-bit version of the ACT245 s Outputs source/sink 24 mA s TTL-compatible inputs
