AS111 RAD-TOL

Rev. 1.1 06/05

Austin Semiconductor, Inc.

PRELIMINARY SPECIFICATION

GENERAL DESCRIPTION

The AS111 is a voltage comparator that has input currents

nearly a thousand times lower than other similar devices. It is

also designed to operate over a wider range of supply voltages:

from standard ±15V op amp supplies down to the single 5V

supply used for IC logic. Their output is compatible with RTL,

DTL and TTL as well as MOS circuits. Further, they can drive

lamps or relays, switching voltages up to 50V at currents as

high as 50 mA.

Both the inputs and the outputs of the AS111 can be

isolated from system ground, and the output can drive loads

referred to ground, the positive supply or the negative supply.

Offset balancing and strobe capability are provided and

outputs can be wire OR’ed. Although slower than some

devices (200 ns response time vs 40 ns), this device is also

much less prone to spurious oscillations.

FEATURES

• Operates from single 5V supply

• Radiation Guaranteed to 100K RADS TID

• Input current: 200 nA max. over temperature

• Offset current: 20 nA max. over temperature

• WIDE Differential input voltage range: ±30V

• Typical Power consumption: 135 mW at ±15V
