TC7MBL3257CFT/FK/FTG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MBL3257CFT,TC7MBL3257CFK,TC7MBL3257CFTG
4-Bit 1-of-2 Multiplexer/Demultiplexer
The TC7MBL3257C is a Low Voltage/Low Capacitance
CMOS 4bit 1-of-2 Multiplexer/Demultiplexer. The low
on-resistance of the switch allows connections to be made with
minimal propagation delay time.
This device consists of four individual two-inputs
multiplexer/demultiplexer with common select input (S) and
output enable ( OE ). The A input is connected to the B1 or B2
outputs as determined by the combination of both the select
input (S) and output enable ( OE ). When the output enable
( OE ) input is held at “H” level, the switches are open
regardless of the state of the select inputs, and a
high-impedance state exists between the switches.
All inputs are equipped with protection circuits against
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
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).

Rise and Fall Times (tr / tf) of the TC7MBL3257C I/O Signals
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 those of the TC7MBL3257C.
The tr(out) / tf(out) values can be approximated as follows. (Figure 3 shows the test circuit.)
tr(out) / 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) = - ( 8 + 15 )E-12 ・ ( 120 + 8.5) ・ ln ( ( ( 3.0 - 0 ) – 1.5 ) / ( 3.0 – 0 ) )
≈ 2.1 ns
Calculation conditions:
VCC = 3.0 V , CL = 15 pF , RDRIVE = 120 Ω (output impedance of the previous IC), VM = 1.5 V (VCC / 2)
Output of the previous IC = digital (i.e., high-level voltage = VCC; low-level voltage = GND)
