74ABT652
Octal Transceivers and Registers with 3-STATE Outputs
General Description
The ABT652 consists of bus transceiver circuits with 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 to HIGH
logic level. Output Enable pins (OEAB, OEBA) are pro-
vided to control the transceiver function.
Features
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
