MC74HCT273A
Octal D FlipâFlop with
Common Clock and Reset
with LSTTLâCompatible
Inputs
HighâPerformance SiliconâGate CMOS
The MC74HCT273A may be used as a level converter for
interfacing TTL or NMOS outputs to HighâSpeed CMOS inputs.
The HCT273A is identical in pinout to the LS273.
This device consists of eight D flipâflops with common Clock and
Reset inputs. Each flipâflop is loaded with a lowâtoâhigh transition of
the Clock input. Reset is asynchronous and active low.
⢠Output Drive Capability: 10 LSTTL Loads
⢠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
⢠In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
⢠Chip Complexity: 284 FETs or 71 Equivalent Gates
