Octal 3-STATE Bus Transceiver and Register

General Description

This device incorporates an octal transceiver and an octal

D-type register configured to enable transmission of data

from bus to bus or internal register to bus.

Features

■ Switching specifications at 50 pF

■ Switching specifications guaranteed over full tempera-

ture and V_CCrange

This bus transceiver features totem-pole 3-STATE outputs

designed specifically for driving highly-capacitive or rela-

tively low-impedance loads. The high-impedance state and

increased high level logic drive provide this device with the

capability of being connected directly to and driving the bus

lines in a bus organized system without need for interface

or pull-up components. They are particularly attractive for

implementing buffer registers, I/O ports, bidirectional bus

drivers, and working registers.

■ Advanced oxide-isolated, ion-implanted Schottky TTL

process

■ 3-STATE buffer-type outputs drive bus lines directly

■ Independent registers and enables for A and B buses

■ Multiplexed real-time and stored data

The registers in the DM74ALS652 are edge-triggered

D-type flip-flops. On the positive transition of the clock

(CAB or CBA), the input data is stored into the appropriate

the A register and the CBA input controls the B register.

The SAB and SBA control pins are provided to select

whether real-time data or stored data is transferred. A LOW

input level selects real-time data and a HIGH level selects

stored data. The select controls have a “make before

break” configuration to eliminate a glitch which would nor-

mally occur in a typical multiplexer during the transition

between stored and real-time data.

The enable (GAB and GBA) control pins provide four

modes of operation: real-time data transfer from bus A to

B, real-time data transfer from bus B to A, real-time bus A

and/or B data transfer to internal storage, or internal stored

data transfer to bus A and/or B.
