FEATURES
Members of the Texas Instruments Widebus™ Family
State-of-the-Art EPIC-IIB™ BiCMOS Design Significantly Reduces Power Dissipation
Latch-Up Performance Exceeds 500 mA Per JESD 70
Typical VOLP (Output Ground Bounce) <1 V at VCC = 5 V, TA = 25°C
Distributed VCC and GND Pin Configuration Minimizes High-Speed Switching Noise
Flow-Through Architecture Optimizes PCB Layout
High-Drive Outputs (–32-mA IOH, 64-mA IOL) Package Options Include Plastic 300-mil
Shrink Small-Outline (DL), Thin Shrink Small-Outline (DGG), and Thin Very Small-Outline (DGV) Packages and 380-mil Fine-Pitch Ceramic Flat (WD) Package Using 25-mil Center-to-Center Spacings
DESCRIPTION
The SN54ABT16244 and SN74ABT16244A are 16-bit buffers and line drivers designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical OE (active-low output-enable) inputs.
