Details
General description The 74HC273; 74HCT273 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the state of their corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A LOW on MRforces the outputs LOW independently of clock and data inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.Features and benefits Input levels: For 74HC273: CMOS level For 74HCT273: TTL level Common clock and master reset Eight positive edge-triggered D-type flip-flops Complies with JEDEC standard no. 7A ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V. Multiple package options Specified from -40℃ to +85℃ and from -40℃ to +125℃

FAQs
What is 74HCT273N?
The 74HCT273N is an octal D-type flip-flop integrated circuit (IC) designed for general-purpose digital logic applications. It is commonly used for data storage, synchronization, and control in digital systems such as microcontrollers, counters, registers, and bus interfacing.
How Does 74HCT273N Work?
The 74HCT273N works by storing a single bit of data in each of its eight flip-flops. The flip-flops capture the input data on a clock edge and maintain the output state until the next clock edge. This enables sequential storage and retrieval of digital information in various digital circuits.
How Many Pins does 74HCT273N have and What are the Functions of the Pinout Configuration?
The 74HCT273N is typically available in a 20-pin DIP (Dual Inline Package) or SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- CP (Clock Pin): Input for clock signal to latch data.
- D0-D7 (Data Pins): Inputs for the data to be stored.
- Q0-Q7 (Output Pins): Outputs for the stored data.
- MR (Master Reset): Reset pin to clear all stored data.
- GND (Ground) and VCC (Power): Power supply and ground pins.
What are the Pros and Cons of 74HCT273N?
Pros:
- Simple Functionality: Easy to use for basic data storage applications.
- Wide Operating Voltage Range: Compatible with both TTL and CMOS logic levels.
- Multiple Package Options: Available in common 20-pin DIP and SOIC packages.
- Cost-Effective: Offers a cost-effective solution for digital logic circuits.
Cons:
- Limited Features: Basic functionality may not be suitable for complex sequential operations.
- No Edge-Triggered Capability: Latches data based on level, not edge transitions.
Are There Any Equivalents/Alternatives to 74HCT273N for Recommendation?
- Equivalent parts to the 74HCT273N include the SN74HC273 from Texas Instruments and the MC74HCT273A from ON Semiconductor.
- Alternative options to the 74HCT273N are the CD40174 from Texas Instruments and the 74HC573 from NXP Semiconductors.
