1. General description

The 74HC7540; 74HCT7540 is an 8-bit inverting buffer/line driver with Schmitt-trigger inputs and

3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes

the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables

the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt trigger

inputs transform slowly changing input signals into sharply defined jitter-free output signals.
