SN74AHCT374DGVR Octal Edge-Triggered D-Type Flip-Flops

The SN74AHCT374DGVR from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop integrated circuit, designed for use in a wide range of digital applications. This device features eight D-type flip-flops with a common clock (CLK) and output enable (OE) inputs, making it an ideal choice for implementing buffer registers, shift registers, and state machines.

Constructed with advanced silicon-gate CMOS technology, the SN74AHCT374DGVR ensures low power consumption while maintaining high-speed operation. It is compatible with both 5V TTL and CMOS logic levels, thanks to its 'AHCT' logic family designation, which provides TTL-compatible inputs and the ability to drive 15 LSTTL loads. The device operates over a broad voltage range of 4.5V to 5.5V, making it versatile for interfacing with a variety of digital systems.

The flip-flops in the SN74AHCT374DGVR capture data on the rising edge of the clock signal, ensuring reliable and predictable data storage. When the output enable (OE) is low, the eight outputs (Q0 to Q7) are active and reflect the data stored in the flip-flops. Conversely, a high OE signal places the outputs in a high-impedance state, effectively disconnecting them from the circuit, which is useful for bus-oriented systems.

Available in a compact 16-pin TSSOP (Thin Shrink Small Outline Package), the SN74AHCT374DGVR is designed for space-constrained applications. The package is also characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide temperature range, which is essential for industrial and automotive applications.

Key features of the SN74AHCT374DGVR include:

• Eight D-type flip-flops with single clock and output enable
• Edge-triggered data input for precise control
• Low power consumption with high-speed operation
• 5V tolerant inputs for interfacing with TTL logic levels
• Supports 4.5V to 5.5V VCC operation
• 3-state outputs for bus interfacing
• Wide operating temperature range: -40°C to 85°C
• Compact 16-pin TSSOP packaging

With its combination of high-speed performance, low power consumption, and robust operating temperature range, the SN74AHCT374DGVR is an excellent choice for designers looking to implement efficient and reliable digital logic systems.
