TOSHIBA TC7WBD126FK

TC7WBD126FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WBD126FK
Dual Bus Switch with Level Shift
The TC7WBD126FK is a low on-resistance, high-speed CMOS
2-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.
The internal diode which adds to power supply line is enable to
realize the shift of signal level from 5 V to 3.3 V. (Note 1)
All inputs are equipped with protector circuits to protect the
device from static discharge.
Weight: 0.01 g (typ.)
Features
•
Operating voltage: VCC = 4.5~5.5 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)
•
TTL level input (control input)
•
Package: US8
±2000 V or more (MIL)
Note 1: In case that over-shoot noise is detected, this device should be used with clamp diode to prevent the next
stage device from over-stress.

Note 2: Typical values are at VCC = 5 V and Ta = 25°C.
Note 3: Measured by the voltage drop between A and B pins at the indicated current through the switch. On
resistance is determined by the lower of the voltages on the two (A or B) pins.
Note 4: Quiescent supply current at VCC = 3.4 V will be sum of ICC and ∆ICC.
