1. Functional Description
•
Dual SPST Bus Switch
2. General
The TC7WB66CFK/L8X and TC7WB67CFK/L8X are low ON-resistance, high-speed CMOS 2-bit bus switches.
These bus switches allow connections or disconnections to be made with minimal propagation delay while
maintaining Low power dissipation which is the feature of CMOS.
TC7WB66CFK/L8Xrequirestheoutputenable(OE)inputtobesetlowtoplacetheoutputintothehighimpedance
state,whereas the TC7WB67CFK/L8X requires the output enable (OE) input to be set high to place the output
into the high impedance.
These Bus switches consist of P-MOS and N-MOS structure, meaning these devices are suitable for analog signal
transmission.
All inputs are equipped with protector circuits to protect the device from static discharge.

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
(“HandlingPrecautions”/“DeratingConceptandMethods”)andindividualreliabilitydata(i.e. reliabilitytestreport
and estimated failure rate, etc).

12. Rise and Fall Time (tr/tf)
The tr(out) and tf(out) values of the output signals are affected by the CR time constant of the input, which consists
of the switch terminal capacitance (CI/O) and the on-resistance (RON) of the input.
In practice, the tr(out) and tf(out) values are also affected by the circuit's capacitance and resistance components
other than the capacitance of TC7WB66CFK/L8X, TC7WB67CFK/L8X
The tr/tf(out) values can be approximated as follows.
(Figure 12.1, Table 12.1 shows the test circuit.)
tr/tf(out) (approx) = - (CI/O + CL) (RDRIVE + RON) ln (((VOH - VOL) - VM) / (VOH - VOL))
Where, RDRIVE is the output impedance of the previous-stage circuit.
Calculation example:
tr(out) (approx) = - (10 + 15) E - 12 (120 + 4) ln (((4.5 - 0) - 2.25) / (4.5 - 0)) = ≈2.1 ns
Calculation conditions:
VCC = 4.5 V, CL = 15 pF, RDRIVE = 120 Ω (output impedance of the previous IC), VM = 2.25 V (VCC/2)
Output of the previous IC = digital (i.e., high-level voltage = VCC, low-level voltage = GND)
