Part Number : SN74CBT16861
Marking : CBT16861
Function : 20-BIT FET BUS SWITCH
Package : SSOP, TSSOP 48 Pin Type
Maker : Texas Instruments
Pinouts : 
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 OEis high, the switch is open, and the high-impedance state exists between the two ports.
Features
1. Member of Texas Instruments’ Widebus Family
2. 5Ω, Switch Connection Between Two Ports
3. TTL-Compatible Input Levels
4. Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
