P1-P3P4-P6P7-P9P10-P12P13-P15P16-P17
74HC241; 74HCT241
Octal buffer/line driver; 3-state
Rev. 3 — 20 February 2018 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.
