74ACT16827DLR [Texas Instruments]

The ACT16827 are noninverting 20-bit buffers composed of two 10-bit sections with separate output-enable signals. For either 10-bit buffer section, the two output-enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section are in the high-impedance state. The devices feature TTL-voltage compatible inputs, 3-state outputs that drive bus lines directly, flow-through architecture for optimized PCB layout, and distributed VCC and GND pin configuration to minimize high-speed switching noise. They are built using EPIC (Enhanced-Performance Implanted CMOS) 1-μm process and offer 500-mA typical latch-up immunity at 125°C. Package options include plastic shrink small-outline (DL) and 380-mil fine-pitch ceramic flat (WD) packages.
