HD74CBT3345
8-bit FET Bus Switch
ADE-205-644 (Z)
Preliminary
Rev. 0
August 2001
Description
The HD74CBT3345 provides eight bits of high speed TTL-compatible bus switching in a standard 鈥?45
device pinout. The low on state resistance of the switch allows connections to be made with minimal
propagation delay. The device is organized as one 8-bit switch bank with dual output enable (OE and
OE)
inputs. When
OE
is low or OE is high, the switch is on, and port A is connected to port B. When
OE
is
high and OE is low, the switch is open, and the high impedance state exists between the two ports.
