SN74CBTS3384

10-BIT FET BUS SWITCH

WITH SCHOTTKY DIODE CLAMPING

SCDS024M – MAY 1995 – REVISED JULY 2003

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265

5-Ω Switch Connection Between Two Ports

TTL-Compatible Input Levels

description/ordering information

The SN74CBTS3384 provides ten bits of

high-speed TTL-compatible bus switching with

Schottky diodes on the I/Os to clamp undershoot.

The low on-state resistance of the switch allows

connections to be made with minimal propagation

delay.

The device is organized as two 5-bit bus switches

with separate output-enable (OE

) inputs. When

is low, the switch is on, and port A is connected

to port B. When OE

is high, the switch is open, and

the high-impedance state exists between the two

ports.
