Functionally and Mechanically Identical to

‘L813, ‘LS14. and ‘LS132, Respectively

P-N-P Inputs Reduce System Loading

Excellent Noise Immunity with Typical

Hysteresis of 0.8 V

description

Each circuit functions as a NAND gate or

inverter, but because of the Schmitt action, it

has different input threshold levels for positive-

going (VT +) and for negative-going (VT-)

signals. The hysteresis or backlash, which is the

difference between the two threshold levels

VT 4+ — VT1-), is typically 800 millivolts.

These circuits are temperature-compensated and

can be triggered from the slowest of input ramps

and still give clean, jitter-free output signals.
