ON Semiconductor MC74HC175AD Quad D Flip-Flop

The MC74HC175AD is a high-performance, silicon-gate CMOS device from ON Semiconductor that embodies the cutting-edge technology in integrated circuit design. This Quad D Flip-Flop is a member of the HC family and is designed to offer both the low power consumption of standard CMOS integrated circuits along with the ability to drive 10 LS-TTL loads.

At the heart of the MC74HC175AD are four edge-triggered flip-flops with individual D-type inputs and complementary Q and Q̅ outputs. These flip-flops are controlled by a common clock (CLK) and a common reset (RESET̅). The reset is asynchronous and active-low, which means it will reset the flip-flops without the need for a clock signal, provided the reset line is held low.

The D inputs to the flip-flops are sampled at the rising edge of the clock. Once the clock goes high, the data present at the D inputs are captured and held at the outputs until the next rising edge of the clock or until the reset input is activated. The high impedance state of the outputs during the power-down mode ensures minimal power consumption and protects the device from potential damage.

With its wide operating voltage range of 2V to 6V, the MC74HC175AD is versatile for use in various applications. It is capable of operating at high speeds, with a typical tpd (propagation delay time) of 13 ns at VCC = 5V. This makes it suitable for high-speed memory storage and retrieval systems, registers, counters, and other sequential logic operations in a broad range of electronics.

The MC74HC175AD comes in a 16-lead SOIC package, which is designed for optimal space-saving on PCBs, making it an excellent choice for compact electronic designs. Its robustness is further enhanced by the chip's latch-up performance, which meets the JEDEC standard JESD78, ensuring reliability under a variety of conditions.

Overall, the MC74HC175AD Quad D Flip-Flop from ON Semiconductor is an essential component for designers looking for a reliable and efficient solution to implement sequential logic in their digital systems.
