54F646 Datasheet (National Semiconductor) - Octal Transceiver/Register

54F646, Octal Transceiver/Register

These devices consist of bus transceiver circuits with TRISTATE 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 goes

54F646 Features
