TC74LCX273F/FW/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX273F,TC74LCX273FW,TC74LCX273FT
Low-Voltage Octal D-Type Flip-Flop with Clear with 5-V Tolerant Inputs and Outputs
The TC74LCX273F/FW/FT is a high-performance CMOS octal
D-type flip-flop. 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.
This 8 bit D-type flip-flop is controlled by a clock input (CK)
and a clear input (CLR). When the CLR input is low, the eight
outputs are at a low logic level.
All inputs are equipped with protection circuits against static
discharge.
Note: xxxFW (JEDEC SOP) is not available in
Japan.
