74AHC273 datasheet


Description :

with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7-A. The 74AHC273, 74AHCT273 has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs.

The common clock (CP) and master reset (MR) inputs, load and reset (clear) all flip-flops simultaneously. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding output (Qn) of the flip-flop.

All outputs will be forced LOW, independent of clock or data inputs, by a LOW on theMR input. The device is useful for applications where only the true output is required and the clock and master reset are common to all storage elements.


1. Balanced propagation delays

2. All inputs have Schmitt-trigger actions

3. Inputs accept voltages higher than VCC

4. Ideal buffer for MOS microcontroller or memory

5. Common clock and master reset
