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.

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two

of which may be realized at the same time.

1. The input and output volta ge ratings may be exceeded even if the input and output clamp-current ratings are

observed.

2. The maximum package power dissipation was calculated using a junction temperature of 150°C.

CC

2. Measured by the voltage drop between the A and B terminals at the indicated current through the switch.

On-state resistance is determined by the lower voltage of the two (A or B) terminals.

3. This is the increase in suppl y current for eac h input that is at the specified TTL voltage level rather than V

or GND.
