FST3126
Quad Bus Switch
General Description
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.
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.
