SCLS238K –OCTOBER 1995–REVISED JUNE 2013

HEX SCHMITT-TRIGGER INVERTERS

Check for Samples: SN74AHC14, SN54AHC14

FEATURES

• Operating Range 2-V to 5.5-V • ESD Protection Exceeds JESD 22

• Latch-Up Performance Exceeds 250 mA Per – 2000-V Human-Body Model (A114-A)

JESD 17

– 200-V Machine Model (A115-A)

– 1000-V Charged-Device Model (C101)

DESCRIPTION

The ’AHC14 devices contain six independent inverters. These devices perform the Boolean function Y = A.

Each circuit functions as an independent inverter, but because of the Schmitt action, the inverters have different

input threshold levels for positive-going (VT+) and negative-going (VT−) signals.
