TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX07F,TC74LCX07FN,TC74LCX07FT
Low-Voltage HEX Buffer with 5-V Tolerant Inputs and Outputs (open drain)
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74LCX07F/FN/FT is a high-performance CMOS buffer.
Designed for use in 3.3-V systems, it achieves high-speed
TC74LCX07F
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) V
applications,
CC
but it could be used to interface to 5-V supply environment for
inputs.
All inputs are equipped with protection circuits against static
discharge.
