Overview
54ACT16825, 74ACT16825 18-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS SCAS155B – JANUARY 1991 – REVISED APRIL 1996 D Members of the Texas Instruments Widebus ™ Family D Inputs Are TTL-Voltage Compatible D Provide Extra Data Width Necessary for Wider Address/Data Paths or Buses With Parity D Flow-Through Architecture Optimizes PCB Layout D Distributed VCC and GND Pin Configuration Minimizes High-Speed Switching Noise D EPIC™ (Enhanced-Performance Implanted CMOS) 1-µm Process D Package Options Include Plastic 300-mil Shrink Small-Outline (DL) Packages Using 25-mil Center-to-Center Pin Spacings and 380-mil Fine-Pitch Ceramic Flat (WD) Packages Using 25-mil Center-to-Center Spacings description The ’ACT16825 18-bit buffers/drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The ’ACT16825 can be used as two 9-bit buffers or one 18-bit buffer.
They provide true data from A to Y.
The 3-state control gate is a 2-input NOR gate; therefore, if either output-enable (OE1 or OE2) input is high, all nine affected outputs are in the high-impedance state.
