TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX08F, TC74LCX08FT, TC74LCX08FK
Low-Voltage Quad 2-Input AND Gate with 5-V Tolerant Inputs and Outputs
The TC74LCX08 is a high-performance CMOS 2-input AND
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 = 2.0 to 3.6 V
• High-speed operation: tpd = 5.5 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, TSSOP and 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.) 08 type

DC output current IOUT ±50 mA
Power dissipation PD 180 mW

Storage temperature Tstg −65 to 150 °C
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: VCC = 0 V
Note 3: High or low state. IOUT absolute maximum rating must be observed.
Note 4: VOUT < GND, VOUT > VCC
