SL74HCT273
Octal D Flip-Flop with Common Clock and Reset
High-Performance Silicon-Gate CMOS
The SL74HCT273 is identical in pinout to the LS/ALS273.
The SL74HCT273 may be used as a level converter for interfacing
TTL or NMOS outputs to High-Speed CMOS inputs.
This device consists of eight D flip-flops with common Clock and
Reset inputs. Each flip-flop is loaded with a low-to-high transition of
the Clock input. Reset is asynchronous and active low.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA
