TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WB126FK
Dual Bus Switch
The TC7WB126FK is a low on-resistance, high-speed CMOS
dual-bit bus switch. This bus switch allows the connections or
disconnections to be made with minimal propagation delay while
maintaining Low power dissipation which is the feature of
CMOS.
When output enable (OE) is at High level, the switch is on;
when at Low level, the switch is off.
All inputs are equipped with protector circuits to protect the
device from static discharge.
Features
· Operating voltage: V
· High speed operation: tpd = 0.25 ns (max)
· Ultra-low on resistance: RON = 5 Ω (typ.)
· Electro-static discharge (ESD) performance: ±200 V or more (JEITA)
±2000 V or more (MIL)
· TTL level input (control input)
· Package: US8
