Octal Registered Transceiver with 3-STATE Outputs

■ Separate controls for data flow in each direction

General Description

■ Guaranteed output skew

The ABT543 octal transceiver contains two sets of D-type

■ Guaranteed multiple output switching specifications

latches for temporary storage of data flowing in either

direction. Separate Latch Enable and Output Enable inputs

are provided for each register to permit independent con-

trol of inputting and outputting in either direction of data

flow.

■ Output switching specified for both 50 pF and 250 pF

loads

■ Guaranteed simultaneous switching noise level and

dynamic threshold performance

■ Guaranteed latchup protection

Features

■ High impedance glitch free bus loading during entire

■ Back-to-back registers for storage

power up and power down cycle

■ Bidirectional data path

■ Nondestructive hot insertion capability

■ A and B outputs have current sourcing capability of 32

mA and current sinking capability of 64 mA
