It stores eight bits of data, with the Q-bar outputs gated by an output-enable line — pull it low to drive the bus, high to float. This makes it a natural fit for microprocessor address/data latch applications where the bus must be shared, or for any 8-bit register that needs bus isolation and inverted polarity. ## 60 MHz clock, 28 ns propagation delay — timing budget matters Rated at 60 MHz clock frequency, with a maximum propagation delay of 28 ns into 50 pF at 6V supply. That 28 ns is the pin-to-pin delay from clock edge to valid output; in a 5V system at 50 pF load, it's the number you budget for setup-and-hold calculations on the receiving device. At 2V the delay stretches, so if you're running near the low end of the 2V–6V supply range, expect slower throughput — derate accordingly for timing closure. ## Military temperature range — not just a commercial part The -55°C to 125°C operating range covers the full military-temperature span. ## Through-hole 20-DIP — legacy board or prototype socket Packaged in a 20-pin DIP (0.300-inch body, 7.62 mm row spacing) with through-hole leads. That's the classic DIP footprint — sockets easily, hand-solders without reflow, and survives in boards where rework access matters. Not a surface-mount part; if your pick-and-place line expects SOIC or SSOP, this won't fit. But for a legacy retrofit, a breadboard prototype, or a high-reliability assembly that avoids BGA, the 20-PDIP is exactly what the BOM specifies. ## Quiescent draw and output drive Quiescent current sits at 8 µA typical — negligible for battery-backed or always-on rails. Output drive is symmetrical at 7.8 mA source and 7.8 mA sink per pin. That's enough to drive a few TTL inputs or a low-power LED indicator, but not enough for a relay coil or a high-capacitance bus without a buffer. Input capacitance is 10 pF per pin, so fan-out on a 5V bus is reasonable — about 10 standard 74HC loads before the rise time degrades. ## Lifecycle and sourcing — active, no LTB risk ROHS3 compliant. For a BOM line that needs a through-hole 8-bit D-type register with tri-state inverted outputs, this part is available through independent distribution and quoted to order against an RFQ.","metaTitle":"CD74HC534E D-Type Flip-Flop, 8-Bit, 60 MHz, 20-DIP","metaDescription":"CD74HC534E 8-bit D-type flip-flop with tri-state inverted outputs. 60 MHz clock, 2V–6V supply, -55°C to 125°C.
