High Speed CMOS Logic
Octal Transparent Latch, Three-State Output
Features
Description
• Common Latch Enable Control
The Harris CD74HC373, CD74HCT373, CD54HC573,
CD74HC573, and CD74HCT573 are high speed Octal Transparent Latches manufactured with silicon gate CMOS technology. They possess the low power consumption of standard
CMOS integrated circuits, as well as the ability to drive 15
LSTTL devices. The CD74HCT373 and CD74HCT573 are
functionally as well as pin compatible with the standard
74LS373 and 74LS573.
• Common Three-State Output Enable Control
• Buffered Inputs
• Three-State Outputs
• Bus Line Driving Capacity
• Typical Propagation Delay = 12ns at VCC = 5V,
CL = 15pF, TA = 25oC (Data to Output for HC373)
The outputs are transparent to the inputs when the latch
enable (LE) is high. When the latch enable (LE) goes low the
data is latched. The output enable (OE) controls the threestate outputs. When the output enable (OE) is high the
outputs are in the high impedance state. The latch operation
is independent to the state of the output enable. The 373 and
573 are identical in function and differ only in their pinout
arrangements.
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs
Ordering Information
• HC Types
- 2V to 6V Operation
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC
at VCC = 5V

NOTES:
5. CPD is used to determine the no-load dynamic power consumption, per latch.
6. PD (total power per latch) = VCC2 fi (CPD + CL) where fi = Input Frequency, CL = Output Load Capacitance, VCC = Supply Voltage.
