FST3384
10-Bit Low Power Bus Switch
General Description
The Fairchild Switch FST3384 provides 10 bits of high-
speed CMOS TTL-compatible bus switches. The low on
resistance of the switch allows inputs to be connected to
outputs without adding propagation delay or generating
additional ground bounce noise. The device is organized
as two 5-bit switches with separate bus enable (OE) sig-
nals. When OE is LOW, the switch is ON and Port A is con-
nected to Port B. When OE is HIGH, the switch is OPEN
and a high-impedance state exists between the two ports.
