| TC74LCX07F/FN/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX07F,TC74LCX07FN,TC74LCX07FT Low-Voltage HEX Buffer with 5-V Tolerant Inputs and Outputs (open drain) The TC74LCX07F/FN/FT 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. Note: xxxFN (JEDEC SOP) is not available in Japan. TC74LCX07F Features * * * * * * * * Low-voltage operation: VCC = 2.0 to 3.6 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 JEDEC SOP, JEITA SOP and TSSOP 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 TC74LCX07FN TC74LCX07FT Weight SOP14-P-300-1.27: 0.18 g (typ.)
