74ABT16245 16-Bit Transceiver with 3-STATE Outputs
General Description
The ABT16245 contains sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte 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 ABT245 s A and B output sink capability of 64 mA, source capability of 32 mA s Guaranteed output skew s Guaranteed multiple output switching specifications s Output switching specified for both 50 pF and 250 pF loads s Guaranteed simultaneous switching noise level and

dynamic threshold performance
s Guaranteed latchup protection s High impedance glitch free bus loading during entire power up and power down cycle s Non-destructive hot insertion capability
