Product specification

Octal transceiver/register, inverting (3-State)

74ABT651

FEATURES

• Independent registers for A and B buses

DESCRIPTION

The 74ABT651 high-performance BiCMOS device combines low

static and dynamic power dissipation with high speed and high

output drive.

• The 74ABT651 is the inverting version of the 74ABT652

• Multiplexed real-time and stored data

• 3-State outputs

The 74ABT651 transceiver/register consists of bus transceiver

circuits with 3-State outputs, D-type flip-flops, and control circuitry

arranged for multiplexed transmission of data directly from the input

bus or the internal registers. Data on the A or B bus will be clocked

into the registers as the appropriate clock pin goes High. Output

Enable (OEAB, OEBA) and Select (SAB, SBA) pins are provided for

bus management.

• Live insertion/extraction permitted.

• Power-up 3-State

• Power-up reset

• Output capability: +64mA/–32mA

• Latch-up protection exceeds 500mA per Jedec Std 17

The following examples demonstrate the four fundamental

bus-management functions that can be performed with the

74ABT651.

• ESD protection exceeds 2000 V per MIL STD 883 Method 3015

The select pins determine whether data is stored or transferred

through the device in real time.

and 200 V per Machine Model

The output enable pins determine the direction of the data flow.
