1 / 14 page SN74CBT16861 20-BIT FET BUS SWITCH SCDS068C – JULY 1998 – REVISED OCTOBER 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Member of Texas Instruments’ Widebus™ Family D 5-Ω Switch Connection Between Two Ports D TTL-Compatible Input Levels D Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II description The SN74CBT16861 provides 20 bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as one dual 10-bit switch with separate output-enable (OE) input. When OE is low, the switch is on, and port A is connected to port B. When OE is high, the switch is open, and the high-impedance state exists between the two ports.
