Quad 1-of-2 Multiplexer/Demultiplexer
The TC7MB3257 is high-speed CMOS quad 1-2
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 inputs is connected to the B1 or B2
outputs determined by the combination both the select input (S)
and output enable ( OE ). When the output enable ( OE ) input is
held “H” level, the switches are open with regardless the state of
select inputs and a high-impedance state exists between the
switches.
All inputs are equipped with protection circuits against static
discharge.
Features
Operating voltage: VCC = 4.5 to 5.5 V
High speed: tpd = 0.25 ns (max)
Low on resistance: RON = 5 Ω (typ.)
ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V
Compatible with TTL outputs (control inputs)
Package: TSSOP16,VSSOP16 (US16)
Pin compatible with the 74xx257 type.
Functionally equivalent to (FST/CBT) 3257.

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).
