TEXAS INSTRUMENTS SN54AHCT16541 SN74AHCT16541 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTShandbook
Update: 28 September, 2023
SN54AHCT16541 and SN74AHCT16541 are 16-bit buffers/drivers with 3-state outputs. They are fabricated using the EPIC (Enhanced-Performance Implanted CMOS) process, and the inputs are TTL-voltage compatible. Distributed VCC and GND pins minimize high-speed switching noise, and the flow-through architecture optimizes PCB layout. The latch-up performance exceeds 250 mA per JESD 17. Package options include plastic shrink small-outline (DL), thin shrink small-outline (DGG), and thin very small-outline (DGV) packages, as well as a 380-mil fine-pitch ceramic flat (WD) package with 25-mil center-to-center spacings. The devices consist of two 8-bit sections with separate output-enable signals. The outputs of each section are active only when both output-enable inputs are low. If either output-enable input is high, the outputs of that section are in the high-impedance state. To ensure the high-impedance state during power up or power down, the output-enable signals should be tied to VCC through pullup resistors, with the minimum value determined by the current-sinking capability of the driver. The SN54AHCT16541 is characterized for operation over the full military temperature range of -55°C to 125°C, while the SN74AHCT16541 is characterized for operation from -40°C to 85°C.
