TECHNICAL DATA
Octal D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
IN74HCT273A
The IN74HCT273A is identical in pinout to the LS/ALS273.
The IN74HCT273A 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
