74AHC244; 74AHCT244 Octal buffer/line driver; 3-state Rev. 6 — 2 July 2020 Product data sheet 1. General description The 74AHC244; 74AHCT244 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 nOE causes the outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. 2. Features and benefits Wide supply voltage range from 2.0 V to 5.5 V Balanced propagation delays All inputs have Schmitt-trigger action Overvoltage tolerant inputs to 5.5 V High noise immunity CMOS low power dissipation Input levels: For 74AHC244: CMOS level For 74AHCT244: TTL level ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V CDM JESD22-C101E exceeds 1000 V Latch-up performance exceeds 100 mA per JESD 78 Class II Level A Multiple package options Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3.
