TC74LCX07F/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX07F, TC74LCX07FK
Low-Voltage HEX Buffer with 5-V Tolerant Inputs and Outputs (open drain)
The TC74LCX07 is a high-performance CMOS buffer. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.
The TC74LCX07 has high performance MOS N-channel transistor. (open-drain outputs)
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.
*IOUT absolute maximum rating must be observed.
Features
• Low-voltage operation: VCC = 1.65 to 5.5 V • High-speed operation: tpz = 3.7 ns (max) (VCC = 3.0 to 3.6 V) • Output current: IOL = 24 mA (min) (VCC = 3.0 V) • Latch-up performance: > −500 mA • Available in JEITA SOP, VSSOP (US) • Open-drain outputs • Power-down protection provided on all inputs and outputs • Pin and function compatible with the 74 series
(74AC/VHC/HC/F/ALS/LS etc.) 07 type

Note 1:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
Note 2: Output in OFF state. IOUT absolute maximum rating must be observed (Output in low state)
Note 3: VOUT < GND
