Features
Description
• Hysteresis on Clock Inputs for Improved Noise
Immunity and Increased Input Rise and Fall Times
• Asynchronous Reset
• Complementary Outputs
• Buffered Inputs
• _TTAyp=ic2a5l_ofC_MAX = 60MHz at V_CC = 5V, C_L = 15pF,
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55^oC to 125^oC
• Balanced Propagation Delay and Transition Times
The Harris CD74HC73 and CD74HCT73 utilize silicon gate
CMOS technology to achieve operating speeds equivalent to
LSTTL parts. They exhibit the low power consumption of
standard CMOS integrated circuits, together with the ability
to drive 10 LSTTL loads.
These flip-flops have independent J, K, Reset and Clock
inputs and Q and Q outputs. They change state on the
negative-going transition of the clock pulse. Reset is
accomplished asynchronously by a low level input. This
device is functionally identical to the HC/HCT107 but differs
in terminal assignment and in some parametric limits.
The 74HCT logic family is functionally as well as pin
compatible with the standard 74LS logic family.
Ordering Information
