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 Wide supply voltage range from 2.0 to 6.0 V CMOS low power dissipation High noise immunity Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Input levels: For 74HC241: CMOS level For 74HCT241: TTL level Octal bus interface Non-inverting 3-state outputs Complies with JEDEC standards JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from 40 C to +85 C and 40 C to +125 C 3.
