Nexperia B.V. Octal buffer/line driver; 3-state 74LVC244APW,112

Description
The 74LVC244A; 74LVCH244A are 8-bit buffer/line drivers with 3-state outputs. The devices can be used as two 4-bit buffers or one 8-bit buffer. Both devices 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 can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. 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. Features and benefits Wide supply voltage range from 1.2 V to 3.6 V CMOS low-power consumption Direct interface with TTL levels Overvoltage tolerant inputs to 5.5 V IOFF circuitry provdes partial Power-down mode operation Bus hold on all data inputs (74LVCH244A only) Complies with JEDEC standard: JESD8-7A (1.65 V to 1.95 V) JESD8-5A (2.3 V to 2.7 V) JESD8-C/JESD36 (2.7 V to 3.6 V) ESD protection: HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V Specified from -40 °C to +85 °C and -40 °C to +125 °C
