Texas Instruments 74ACT16640
The 74ACT16640 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area. The 54ACT16640 is characterized for operation over the full military temperature range of –55°C to 125°C. The 74ACT16640 is characterized for operation from –40°C to 85°C.54ACT16640, 74ACT16640 16-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCAS173A - JULY 1990 - REVISED APRIL 1996 D Members of the Texas Instruments Widebus ™ Family D Inputs Are TTL-Voltage Compatible 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 500-mA Typical Latch-Up Immunity at 125°C D Packaged in 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 ’ACT16640 are inverting 16-bit transceivers designed for asynchronous communication between data buses. These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (1DIR and 2DIR) inputs. The output-enable (1OE and 2OE) inputs can be used to disable the device so that the buses are effectively isolated.
