74F646 Datasheet - Fairchild

74F646 Octal Transceiver/Register

These devices consist of bus transceiver circuits with 3STATE, 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 goe.

74F646 Features

* s Independent registers for A and B buses s Multiplexed real-time and stored data s 74F648 has inverting data paths s 74F646/74F646B have non-inverting data paths s 74F646B is a faster version of the 74F646 s 3-STATE outputs s 300 mil slim DIP Ordering Code: Order Number 74F646SC 74F646MSA 74F646SP
