TC74VCX157FT
1. Functional Description
•
Low-Voltage Quad 2-Channel Multiplexer with 3.6-V Tolerant Inputs and Outputs
2. General
The TC74VCX157FT is a high performance CMOS multiplexer which is guaranteed to operate from 1.2 V to 3.6
V. Designed for use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high. speed operation while maintaining
the CMOS low power dissipation.
It is also designed with over voltage tolerant inputs and outputs up to 3.6 V.
It consists of four 2-input digital multiplexers with common select and strobe inputs.
When the ST input is held "H" level, selection of data is inhibited and all the outputs become "L" level. The
SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs.
All inputs are equipped with protection circuits against static discharge.
3. Features
(1)
Wide operating temperature range: Topr = -40 to 125 � (Note 1)
(2)
Low-voltage operation: VCC = 1.2 to 3.6 V
(3)
High-speed operation: tpd = 3.0 ns (max) (VCC = 3.0 to 3.6 V)
tpd = 3.5 ns (max) (VCC = 2.3 to 2.7 V)
tpd = 7.0 ns (max) (VCC = 1.65 to 1.95 V)
tpd = 14.0 ns (max) (VCC = 1.4 to 1.6 V)
tpd = 35.0 ns (max) (VCC = 1.2 V)
(4)
Output current: IOH/IOL = ±24 mA (min) (VCC = 3.0 V)
IOH/IOL = ±18 mA (min) (VCC = 2.3 V)
IOH/IOL = ±6 mA (min) (VCC = 1.65 V)
IOH/IOL = ±2 mA (min) (VCC = 1.4 V)
(5) 3.6 V tolerant function and power-down protection provided on all inputs and outputs.
Note 1: Operating Range spec of Topr = -40 � to 125 � is applicable only for the products which manufactured after
April 2020.

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).
Note 1: VCC = 0 V
Note 2: High (H) or Low (L) state. IOUT absolute maximum rating must be observed.
Note 3: VOUT < GND, VOUT > VCC
Note 4: 180 mW in the range of Ta = -40 to 85 �. From Ta = 85 to 125 � a derating factor of -3.25 mW/� shall be
applied until 50 mW.
