TC74LVX273F/FW/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LVX273F,TC74LVX273FW,TC74LVX273FT
Octal D-Type Flip-Flop with Clear
The TC74LVX273F/ FW/ FT is a high-speed CMOS octal D-flip
flop fabricated with silicon gate CMOS technology. Designed for
use in 3-V systems, it achieves high-speed operation while
maintaining the CMOS low power dissipation.
This device is suitable for low-voltage and battery operated
systems.
Information signals applied to D inputs are transferred to the
Q outputs on the positive going edge of the clock pulse.
When the CLR input is held low, the Q outputs are in the low
logic level independent of the other inputs.
An input protection circuit ensures that 0 to 5.5V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5V to 3V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
Note: xxxFＷ (JEDEC SOP) is not available in
Japan.
