Renesas 74HC273FPDV-E

Overview

74HC273FPDV-E from Renesas Electronics is an octal D-type master-slave flip-flop with synchronous clock and asynchronous active-low clear, operating across 2–6 V supply, delivering 18 ns typical clock-to-Q propagation delay (CL = 50 pF), fanout of 10 LSTTL loads, and ±25 mA output drive - used in digital control registers, address latching, and data synchronization in industrial logic systems.

For engineers reviewing the 74HC273FPDV-E datasheet, 74HC273FPDV-E pinout, 74HC273FPDV-E application, or 74HC273FPDV-E equivalent, key selection criteria include guaranteed operation from –40°C to +85°C, low static ICC ≤ 4 µA at 25°C, input voltage thresholds compatible with both HC and TTL logic families, and SOP-20 package compatibility with automated PCB assembly.

Technical Context

This device implements eight independent edge-triggered D flip-flops sharing a common clock input and a globally asserted asynchronous clear. Each stage transfers data from D to Q on the rising edge of Clock only when Clear is high; asserting Clear low forces all Q outputs low regardless of clock or D state.

It uses silicon-gate CMOS technology for rail-to-rail output swing, low power consumption, and noise immunity. Input thresholds are defined relative to VCC (VIH ≥ 3.15 V at VCC = 4.5 V; VIL ≤ 1.35 V), and output drive capability supports direct interfacing with LSTTL loads without pull-up resistors.

FAQ

What is the maximum clock frequency supported by the 74HC273FPDV-E?

The 74HC273FPDV-E supports a maximum clock frequency of 28 MHz over its full operating temperature range (–40°C to +85°C) at VCC = 4.5 V, and up to 35 MHz at 25°C. This is derived from its specified propagation delay (tPHL/tPLH ≤ 36 ns at –40°C to +85°C, CL = 50 pF), ensuring robust timing margin in synchronous logic designs using the 74HC273FPDV-E.

Does the 74HC273FPDV-E have Schmitt-trigger inputs?

No, the 74HC273FPDV-E does not feature Schmitt-trigger inputs. Its input thresholds are standard CMOS levels (VIH ≥ 3.15 V, VIL ≤ 1.35 V at VCC = 4.5 V), with no hysteresis. Signal integrity must be maintained externally - slow-rising or noisy clock/data lines require conditioning before connection to the 74HC273FPDV-E.

Can the 74HC273FPDV-E operate reliably at 3.3 V supply?

Yes, the 74HC273FPDV-E is fully specified for operation at 3.3 V (within its 2–6 V range). At VCC = 3.3 V, VIH is guaranteed ≥ 2.31 V and VIL ≤ 1.09 V, and tPHL/tPLH remains ≤ 40 ns (–40°C to +85°C), making the 74HC273FPDV-E suitable for mixed-voltage 3.3 V/5 V systems without level translation.

Is the 74HC273FPDV-E pin-compatible with the 74HCT273?

No, the 74HC273FPDV-E is not pin-compatible with the 74HCT273. While both are 20-pin SOP octal D flip-flops with identical pin numbering, the 74HCT273 uses TTL-compatible input thresholds (VIH = 2.0 V min) and is rated only for 4.5–5.5 V operation - unlike the 74HC273FPDV-E's 2–6 V range and higher VIH. Interchange requires validation of input drive strength and voltage margins.

What is the meaning of "FPDV-E" in the 74HC273FPDV-E part number?

"FPDV-E" denotes Renesas' package and marking code: "FP" = SOP-20 (JEITA), "D" = standard plastic body, "V" = lead-free Ni/Pd/Au plating, and "E" = tape-and-reel packaging (2,000 pcs/reel). This matches the HD74HC273FPEL ordering code in Renesas documentation, confirming the 74HC273FPDV-E is the commercial-grade, RoHS-compliant, surface-mount variant of the HD74HC273.
