FST3126
4-Bit 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.
Features
s 4
switch connection between two ports.
s Minimal propagation delay through the switch.
s Low lCC.
s Zero bounce in flow-through mode.
s Control inputs compatible with TTL level.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
