SN74ALVCH16240 Datasheet | Texas Instruments

FEATURES - Member of the Texas Instruments Widebus™ Family - EPIC™ (Enhanced-Performance Implanted CMOS) Submicron Process - ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 p F, R = 0) - Latch-Up Performance Exceeds 250 m A Per JESD 17 - Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors - Package Options Include Plastic 300-mil Shrink Small-Outline (DL) and Thin Shrink Small-Outline (DGG) Packages DESCRIPTION This 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation. The SN74ALVCH16240 is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides inverting outputs and symmetrical active-low output-enable (OE) inputs.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. The SN74ALVCH16240 is characterized for operation from -40°C to 85°C.
