74HC7541; 74HCT7541

Octal Schmitt trigger buffer/line driver; 3-state

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