54ABT16646 Datasheet (National Semiconductor) - 16-Bit Transceivers/Registers

54ABT16646, 16-Bit Transceivers/Registers

The ’ABT16646 consists of bus transceiver circuits with TRI-STATE, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers.

Data on the A or B bus will be clocked into the registers as the appropriate clock pin

54ABT16646 Features

* n Independent registers for A and B buses n Multiplexed real-time and stored data n A and B output sink capability of 48 mA, source capability of 24 mA n Guaranteed latchup protection n High impedance glitch free bus loading during entire power up and power down cycle n Nondestructive hot insertion
