1. General description

The 74HC7541; 74HCT7541 is an 8-bit 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.
