FST3126

4-Bit Bus Switch

General Description

Features

The Fairchild Switch FST3126 provides four high-speed

CMOS TTL-compatible bus switches. The low on resis-

tance of the switch allows inputs to be connected to out-

puts without adding propagation delay or generating

additional ground bounce noise.

■ 4Ω switch connection between two ports.

■ Minimal propagation delay through the switch.

■ Low l_CC

■ Zero bounce in flow-through mode.

■ Control inputs compatible with TTL level.

The device is organized as four 1-bit switches with sepa-

rate OE inputs. When OE is HIGH, the switch is ON and

Port A is connected to Port B. When OE is LOW, the switch

is OPEN and a high-impedance state exists between the

two ports.
