HD74CBT1G125
Single FET Bus Switch
ADE-205-645 (Z)
Rev. 0
Jan. 2002
Description
The HD74CBT1G125 features a single high-speed line switch. The switch is disabled when the output
enable (OE) input is high.
Features
• Minimal propagation delay through the switch.
• 5 Ω switch connection between two ports.
• TTL-compatible input levels.
• Ultra low quiescent power.
-Ideally suited for notebook applications.

Note: 1. The propagation delay is the calculated RC time constant of the typical on-state resistance of the
switch and the specified load capacitance, when driven by an ideal voltage source (zero output
impedance).
