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).
