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 IOFF. The IOFF circuitry 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.
