Low Voltage Quad 2-Channel Multiplexer with 5 V Tolerant Inputs and Outputs
The TC74LCX157 is a high-performance CMOS multiplexer.
Designed for use in 3.3-V systems, it achieves high-speed
operation while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (3.3 V) V_CC applications,
but it could be used to interface to 5-V supply environment for
inputs.
It consists of four 2-input digital multiplexers with common
SELECT and ST 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.
Features
• Low-voltage operation: V_CC = 1.65 to 3.6 V
• High-speed operation: t_pd = 5.8 ns (max) (V_CC = 3.0 to 3.6 V)
• Ouput current: |I_OH|/I_OL = 24 mA (min) (V_CC = 3.0 V)
• Latch-up performance: ＞±500 mA
• Available in JEITA SOP, TSSOP and VSSOP (US)
• Power-down protection provided on all inputs and outputs
• Pin and function compatible with the 74 series
(74AC/VHC/HC/F/ALS/LS etc.) 157 type
