AS161

Rev. 0.3 6/05

Austin Semiconductor, Inc.

GENERAL DESCRIPTION

The LM161 is a very high speed differential input,

complementary TTL output voltage comparator with improved

characteristics over similar devices for which it is a pin-for-pin

replacement. The device has been optimized for greater speed

performance and lower input offset voltage. Typically delay

varies only 3 ns for over-drive variations of 5 mV to 500 mV. It

may be operated from op amp supplies (±15V).

Complementary outputs having maximum skew are provided.

Applications involve high speed analog to digital converters

and zero-crossing detectors in disk file systems.

FEATURES

• Independent strobes

• High Speed: 20ns Max

• Tight delay matching on both outputs

• Complementary TTL outputs

• Operates from op amp supplies: ±15V

• Low speed variation with overdrive variation

• Low input offset voltage

• Versatile supply voltage range
