SN74ABT273PWRG4 Octal D-Type Flip-Flop by Texas Instruments

The SN74ABT273PWRG4 from Texas Instruments is a high-performance octal D-type flip-flop with a clear feature. Designed for 5-V VCC operation, this device is particularly well-suited for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

With its octal configuration, the SN74ABT273PWRG4 contains eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The clear function for all flip-flops is achieved through a single input (CLR), providing a convenient method to reset the entire device to a known state. When the CLR input is taken low, all Q outputs are set to a low level irrespective of the other inputs.

The device features a wide operating temperature range from -40°C to 85°C, making it suitable for industrial applications. The SN74ABT273PWRG4 has a typical tpd (propagation delay time) of 3.6 ns, ensuring fast response times for high-speed data processing needs.

Constructed with Texas Instruments' BiCMOS technology, the SN74ABT273PWRG4 combines the low power dissipation of CMOS with the high-speed operation of bipolar transistors. This technology makes the device an excellent choice for interfacing with high-speed microprocessors without the need for external resistors.

The device is offered in a TSSOP (Thin Shrink Small Outline Package) form factor with a 20-pin configuration, designated as PWRG4. This package is optimized for reduced space on PCBs, providing a compact solution for designers.

Key features of the SN74ABT273PWRG4 include:

• Eight edge-triggered D-type flip-flops with individual D inputs and Q outputs
• Single-rail clear input
• 3-state outputs for bus-oriented applications
• Outputs source/sink 24 mA
• Typical VOLP (Output Ground Bounce) < 0.8V at VCC = 5V, TA = 25°C
• Typical VOHV (Output VOH Undershoot) > 2V at VCC = 5V, TA = 25°C

The SN74ABT273PWRG4 is a robust, high-speed flip-flop component that provides reliable performance for a wide range of digital applications. Its ability to quickly clear its state and its high drive capabilities make it a versatile choice for system designers.
