74HC241; 74HCT241

Octal buffer/line driver; 3-state

Rev. 4 — 15 July 2021

Product data sheet

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 V_CC

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

levels.

2. Features and benefits
