Texas Instruments 74ACT16646
The 74ACT16646 is packaged in TI’s shrink small-outline package, which provides twice the functionality of standard small-outline packages in the same printed-circuit-board area. The 54ACT16646 is characterized for operation over the full military temperature range of –55°C to 125°C. The 74ACT16646 is characterized for operation from –40°C to 85°C.D Members of the Texas Instruments Widebust Family D Inputs Are TTL-Voltage Compatible D Independent Registers for A and B Buses D Multiplexed Real-Time and Stored Data D Flow-Through Architecture Optimizes PCB Layout D Distributed VCC and GND Pin Configuration Minimizes High-Speed Switching Noise D EPICt (Enhanced-Performance Implanted CMOS) 1-mm Process D 500-mA Typical Latch-Up Immunity at 125°C 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 Pin Spacings description The ’ACT16646 are 16-bit bus transceivers consisting of D-type flip-flops and control circuitry with 3-state outputs arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. The devices can be used as two 8-bit transceivers or one 16-bit transceiver. Data on the A or B bus is clocked into the registers on the low-to-high transition of the appropriate clock (CLKAB or CLKBA) input.
