HD74CBT1G126
Single FET Bus Switch
REJ03D0816-0100
(Previous: ADE-205-661)
Rev.1.00
Apr 07, 2006
Description
The HD74CBT1G126 features a single high-speed line switch. The switch is disabled when the output enable (OE)
input is low.
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.
• Ordering Information
