1. General description

The 74HC241; 74HCT241 is an 8-bit buffer/line driver with 3-state outputs. The device can be used

as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE),

each controlling four of the 3-state outputs. A HIGH on 1OE or LOW on 2OE causes the associated

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.

The 74HCT241 device features reduced input threshold levels to allow interfacing to TTL logic

levels.
