TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WBL126AFK
Low-Voltage Dual Bus Switch
The TC7WBL126AFK provides two bits of low-voltage
high-speed bus switching. The low ON-resistance of the switch
allows connections to be made with minimal propagation delay
and while maintaining CMOS low power dissipation.
The device comprises dual 2-bit switches with separate bus
enable (OE) signals. When OE is high, the switch is on and port A
is connected to port B. When OE is low, the switch is off and a
high-impedance state exists between the two ports.
All inputs are equipped with protection circuits to guard
against static discharge.
Weight: 0.01 g (typ.)
Features
Operating voltage range: VCC = 2 to 3.6 V
High speed: tpd = 0.31 ns (max) @ 3 V
Ultra-low ON-resistance: RON = 5 (typ.) @ 3 V
ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V
Power-down protection provided on inputs (OE input only)
Package: US8

Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
