1 / 13 page SN74ALB16244 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS SCBS647D – AUGUST 1995 – REVISED JANUARY 2001 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Member of Texas Instruments’ Widebus Family D State-of-the-Art Advanced Low-Voltage BiCMOS (ALB) Technology Design for 3.3-V Operation D Schottky Diodes on All Inputs to Eliminate Overshoot and Undershoot D Industry Standard ’16244 Pinout D Distributed VCC and GND Pins Minimize High-Speed Switching Noise D Flow-Through Architecture Optimizes PCB Layout description The SN74ALB16244 16-bit buffer and line driver is designed for high-speed, low-voltage (3.3-V) VCC operation. This device is intended to replace the conventional driver in any speed-critical path. The small propagation delay is achieved using a unity-gain amplifier on the input and feedback resistors from input to output, which allows the output to track the input with a small offset voltage. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device provides true outputs and symmetrical active-low output-enable (OE) inputs.
