ABT162827A is a 20-bit non-inverting buffer from TI with independent output enable signals. The output ports have equivalent 25-ohm series resistors, so no external resistors are required. During power on and off, it is in the high impedance state. The typical VOLP (output ground bounce) is less than 1V at VCC=5V, TA=25°C. Distributed VCC and GND pins minimize high-speed switching noise. Ioff and power-up 3-state support hot insertion. The flow-through architecture optimizes PCB layout. Latch-up performance exceeds 500 mA per JEDEC Standard JESD-17. ESD protection exceeds JESD 22 - 2000-V Human-Body Model (A114-A) - 200-V Machine Model (A115-A)
The document provides technical specifications, electrical characteristics, and switching parameters for the Widebus™ family of 20-bit buffers. These noninverting devices are composed of two 10-bit buffers with separate output-enable signals designed to source or sink up to 12 mA.
Key features include equivalent 25-Ω series resistors to reduce overshoot and undershoot, high-impedance states during power-up and power-down to prevent driver conflict, and latch-up performance exceeding JEDEC standards. The datasheet covers ordering information for various packages including SSOP, TSSOP, and CFP.
| High-level Output Current (IOH) | -3 mA to -12 mA |
|---|---|
| Low-level Output Current (IOL) | 8 mA to 12 mA |
| Operating Temperature Range (SN54ABT162827A) | -55°C to +125°C |
