IK Semicon IN74HCT273A Octal d flip-flop with common clock and reset high-performance silicon-gate cmo Datasheet

TECHNICAL DATA
IN74HCT273A
Octal D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
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

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
