SN74AUCH244 Datasheet (Texas Instruments)

SN74AUCH244, OCTAL BUFFER/DRIVER

ordering information This octal buffer/driver is operational at 0.8-V to 2.7-V VCC, but is designed specifically for 1.65-V to 1.95-V VCC operation.

The SN74AUCH244 is organized as two 4-bit line drivers with separate output-enable (OE) inputs.

When OE is low, the device passes data from the A input

D Optimized for 1.8-V Operation and is 3.6-V I/O Tolerant to Support Mixed-Mode Signal Operation D Ioff Supports Partial-Power-Down Mode Operation D Sub 1-V Operable D Max tpd of 1.9 ns at 1.8 V D Low Power Consumption, 20-µA Max ICC D ±8-mA Output Drive at 1.8 V D Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors D Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II D ESD Protection Exceeds JESD 22 2000-V Human-Body Model (A114-A) 200-V
