TOSHIBA TC7WBL125FK

TC7WBL125FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TENTATIVE
TC7WBL125FK
Dual Low-Voltage Bus Switch
The TC7WBL125FK is a low on-resistance, high-speed CMOS
2-bit bus switch with low voltage operation. 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 low level, the switch is on; when
at high level, the switch is off.
P-MOS and N-MOS channel block also allows that the device is
suitable for analog signal transmission.
All inputs are equipped with protection circuits to protect the
device from static discharge.
Weight: 0.01 g (typ.)

Note 1: The typical values are at VCC = 3.3 V, Ta = 25°C.
Note 2: The typical values are at VCC = 2.5 V, 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 two (A or B) pins.

Note 4: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay
other than the RC delay of the typical on resistance of the switch and the 50 pF load capacitance, when
driven by an ideal voltage the source (zero output impedance).
