Low-
Voltage 3-to-8 Line Decoder with 5-V Tolerant Inputs and Outputs
The TC74LCX138 is a high-performance
CMOS 3-to-8 decoder. 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) VCC applications, but it could be used to interface to 5-V supply environment for inputs.
When the device is enabled, 3 binary select inputs (A, B and C) determine which one of the outputs ( Y0 - Y7 ) will go low. When enable input G1 is held low or either G2A or G2B is held high, decoding function is inhibited and all outputs go high.
G1, G2A , and G2B inputs are provided to ease cascade connection and for use as an address decoder for memory systems.
All inputs are equipped with protection circuits against static discharge.
Features
Low-
voltage operation: VCC = 1.65 to 3.6 V High-speed operation: tpd = 6.0 ns (max) (VCC = 3.0 to 3.6 V) Ouput current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) Latch-up performance: >±500 mA Available in JEITA SOP, 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.) 138 type
