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 â245
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.
Features
⢠Standard â245 type pinout.
⢠Minimal propagation delay through the switch.
⢠5 ⦠switch connection between two ports.
⢠TTL-compatible input levels.
⢠Ultra low quiescent power.
-Ideally suited for notebook applications.
