1 / 13 page SN54CBT16244, SN74CBT16244 16-BIT FET BUS SWITCHES SCDS031I – MAY 1996 – REVISED OCTOBER 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Members of Texas Instruments’ Widebus™ Family D Standard ’16244-Type Pinout D 5-Ω Switch Connection Between Two Ports D TTL-Compatible Input Levels description The ’CBT16244 devices provide 16 bits of high-speed TTL-compatible bus switching in a standard ’16244 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. These devices are organized as four 4-bit low-impedance switches with separate output-enable (OE) inputs. When OE is low, the switch is on, and data can flow from port A to port B, or vice versa. When OE is high, the switch is open, and the high-impedance state exists between the two ports.
