Product details

Overview

V62/05621-01XE from Texas Instruments is a single positive-edge-triggered D-type flip-flop IC designed for high-reliability military and aerospace timing control. It operates across 1.65 V to 5.5 V V_CC, delivers 5 ns max t_pd at 3.3 V, supports I_off partial-power-down mode, and is qualified for –55°C to 115°C operation in SC-70 (DCK) package.

For engineers reviewing the V62/05621-01XE datasheet, V62/05621-01XE pinout, V62/05621-01XE application, or V62/05621-01XE equivalent, this device serves as a radiation-tolerant, low-power edge-triggered storage element in synchronous logic, clock-domain interfacing, and secure data latching where extended temperature range and controlled baseline manufacturing are mandatory.

Technical Context

This device implements a single-bit synchronous storage cell with positive-edge clock triggering, where data at the D input transfers to Q only on the rising voltage threshold of CLK-not dependent on edge slew rate. Its I_off circuitry actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion and multi-rail system integration.

Designed for 1.65–5.5 V operation, it accepts input voltages up to 5.5 V independent of V_CC, provides ±24 mA output drive at 3.3 V, and meets JESD 78 Class II latch-up immunity (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 200-V MM, 1000-V CDM).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - Enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters.
Max Propagation Delay	5 ns at 3.3 V - Supports >160 MHz clock frequency in high-speed control loops and data sampling paths.
I_off Support	Active during power-down - Prevents damaging current flow between powered and unpowered rails in partial-power-down systems.
Output Drive	±24 mA at 3.3 V - Drives multiple LVC loads or resistive termination without external buffers.
Operating Temperature	–55°C to 115°C - Qualified for extended-range deployment in avionics, downhole tools, and space-qualified electronics.
Input Voltage Tolerance	Up to 5.5 V regardless of V_CC - Allows mixed-voltage interface with legacy 5 V peripherals while powered from lower V_CC.
Power Consumption	10 µA max I_CC - Minimizes quiescent current in battery-backed or always-on monitoring subsystems.

Pinout & Package

SC-70 (DCK) 5-pin surface-mount package: 1.25 mm × 2.1 mm footprint, 1.1 mm max height, JEDEC MO-203 compliant, moisture sensitivity level 1 (260°C peak reflow).

Pin/Terminal	Circuit Role	Design Meaning
1 - D	Data Input	Asynchronous data source synchronized to CLK edge; must meet setup/hold timing (e.g., 1.2 ns t_su at 3.3 V).
2 - GND	Ground Reference	Primary return path for all internal logic and output currents; requires low-impedance PCB connection.
3 - CLK	Clock Input	Positive-edge-sensitive trigger; transition recognized at voltage threshold, not edge slope - immune to slow-rising clocks.
4 - Q	True Output	Non-inverted registered output; drives downstream logic with rail-to-rail swing and ±24 mA capability at 3.3 V.
5 - V_CC	Supply Voltage	Single power rail supporting 1.65–5.5 V; powers internal logic and output buffers; bypass capacitor required.

Key Features

Feature	Design Value
Controlled Baseline Manufacturing	Single assembly/test site and single fabrication site ensure consistent parametric performance and traceable lot history for defense programs.
Extended Product Life Cycle	Guaranteed long-term availability with extended product-change notification - critical for 10+ year aerospace platform sustainment.
Partial-Power-Down (I_off)	Outputs enter high-impedance state when V_CC = 0 V, eliminating backfeed risk in multi-supply systems during power sequencing.
Latch-Up Immunity	Exceeds 100 mA per JESD 78 Class II - ensures robustness against transient overvoltage events in harsh EMI environments.
ESD Protection	2000-V HBM, 200-V MM, 1000-V CDM - exceeds MIL-STD-883 requirements for handling and board-level reliability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar D-type flip-flop applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G79WDCKREP	Same silicon, commercial-temp version (–40°C to 125°C), non-extended life cycle, no defense qualification.	Approved for industrial automation but lacks MIL-PRF-38535 screening and extended product change notification.	Select when cost sensitivity outweighs long-term supply assurance and extreme temperature coverage.
SN74LVC1G79-Q1	Automotive-qualified (AEC-Q100 Grade 1), same SC-70 package, identical electrical specs, different test flow and traceability.	Validated for automotive safety-critical systems (ISO 26262 ASIL-B), not rated for defense/aerospace environmental stress profiles.	Choose for transportation applications requiring zero-defect reliability but not military temperature or radiation tolerance.

Compared with SN74LVC1G79WDCKREP and SN74LVC1G79-Q1, V62/05621-01XE uniquely combines extended temperature range (–55°C to 115°C), defense-grade manufacturing controls, and guaranteed long-life supply-making it irreplaceable in mission-critical aerospace platforms where component obsolescence or thermal derating cannot be tolerated.

FAQ

What is the maximum clock frequency supported by V62/05621-01XE?

V62/05621-01XE supports a maximum clock frequency of 160 MHz across its full operating voltage and temperature range. This is validated by timing parameters including t_w (minimum pulse width) of 2.5 ns and t_pd (propagation delay) as low as 1 ns at 5 V, enabling use in high-speed digital control and data capture circuits where deterministic edge alignment is essential.

Does V62/05621-01XE support partial-power-down operation?

Yes, V62/05621-01XE features I_off circuitry that disables outputs when V_CC = 0 V, preventing damaging current backflow in multi-rail systems.
