Low-Voltage Quad 2-Input NOR Gate - Toshiba Semiconductor
Description
TC74LCX02F/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX02F, TC74LCX02FK
Low-Voltage Quad 2-Input NOR Gate with 5-V Tolerant Inputs and Outputs
The TC74LCX02 is a high-performance CMOS 2-input NOR gate.
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.
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 = 5.
2 ns (max) (VCC = 3.
0 to 3.
6 V) • Output 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.
