Texas Instruments 74AC11873
The 74AC11873 is characterized for operation from – 40°C to 85°C.74AC11873 DUAL 4-BIT D-TYPE LATCH WITH 3-STATE OUTPUTS SCAS095 – JANUARY 1990 – REVISED APRIL 1993
● 3-State Buffer-Type Outputs Drive Bus Lines Directly
● Bus-Structured Pinout
● Flow-Through Architecture Optimizes PCB Layout
● Center-Pin VCC and GND Configurations Minimize High-Speed Switching Noise
● EPIC™ (Enhanced-Performance Implanted CMOS) 1-µm Process
● 500-mA Typical Latch-Up Immunity at 125°C description This dual 4-bit transparent D-type latch features 3-state outputs designed specifically for bus driving. This makes these devices particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
