Overview
TC74LCX244F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX244F, TC74LCX244FK Low-Voltage Octal Bus Buffer with 5-V Tolerant Inputs and Outputs The TC74LCX244 is a high-performance CMOS octal bus buffer.
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 both inputs and outputs.
The TC74LCX244 is a non-inverting 3-state buffer having two activelow output enables.
This device is designed to be used with 3-state memory address drivers, etc.
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.
5 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.
