TC74LCX138F Datasheet

Low-Voltage 3-to-8 Line Decoder with 5-V Tolerant Inputs and Outputs


The TC74LCX138F 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) VCCapplications, but it could be used to interface to 5-V supply environment for inputs. TC74LCX138F 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 JEDEC SOP, JEITA SOP, TSSOP and VSSOP (US) • Power-down protection providedon all inputs and outputs • Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 138 type
