74ALVC244 Octal buffer/line driver 3-state Rev. 5 30 April 2021 Product data sheet 1. General description The 74ALVC244 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. This device is fully specified for partial power down applications using I . The I circuitry OFF OFF disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2. Features and benefits Wide supply voltage range from 1.65 V to 3.6 V 3.6 V tolerant inputs/outputs CMOS low power consumption Direct interface with TTL levels (2.7 V to 3.6 V) Power-down mode Latch-up performance exceeds 250 mA Complies with JEDEC standards: JESD8-7 (1.65 V to 1.95 V) JESD8-5 (2.3 V to 2.7 V) JESD8B (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 C to +85 C 3.
