IN74ACT273 Datasheet, PDF (1/5 Pages) Integral Corp. – OCTAL D FLIP-FLOP WITH COMMON CLOCK AND RESET

IN74ACT273
OCTAL D FLIP-FLOP WITH
COMMON CLOCK AND RESET
High-Speed Silicon-Gate CMOS
The IN74ACT273 is identical in pinout to the LS/ALS273,
HC/HCT273. The IN74ACT273 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; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
