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) Latch-up performance: -300 mA
(6) ESD performance: Human Body Model ≥ ±2000 V
(7) 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.
