Features
Description
• True and Complementary Outputs
• Buffered Inputs and Outputs
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
The ’HC75 and ’HCT75 are dual 2-bit bistable transparent
latches. Each one of the 2-bit latches is controlled by
separate Enable inputs (1E and 2E) which are active LOW.
When the Enable input is HIGH data enters the latch and
appears at the Q output. When the Enable input (1E and 2E)
is LOW the output is not affected.
Ordering Information
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs
• HC Types
- 2V to 6V Operation
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC
at VCC = 5V
• HCT Types
- 4.5V to 5.5V Operation
- Direct LSTTL Input Logic Compatibility,
VIL= 0.8V (Max), VIH = 2V (Min)
- CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH
