Product details
Overview
V62/06605-01XE from Texas Instruments is a dual positive-edge-triggered D-type flip-flop IC operating from 2 V to 5.5 V, featuring 14-pin TSSOP (PW) packaging, 13 ns max propagation delay at 5 V, Ioff partial-power-down support, and extended temperature range from –55°C to 125°C - used in radiation-tolerant aerospace timing control and synchronous logic state retention.
For engineers reviewing the V62/06605-01XE datasheet, V62/06605-01XE pinout, V62/06605-01XE application, or V62/06605-01XE equivalent, key selection considerations include its qualified enhanced-product pedigree for high-reliability environments, mixed-mode voltage operation across all ports, latch-up immunity (>250 mA per JESD 17), and guaranteed performance under extended temperature stress.
Technical Context
This device implements two independent edge-triggered D flip-flops with asynchronous preset (PRE) and clear (CLR) inputs active-low, enabling immediate output forcing regardless of clock or data state. Each section operates with setup time as low as 3 ns and hold time up to 2.15 ns at 5 V, supporting reliable sampling of high-speed digital signals in deterministic control paths.
The internal logic uses LVCMOS-compatible input thresholds (VIH = 0.7×VCC, VIL = 0.3×VCC), rail-to-rail output swing (VOH ≥ VCC–0.1 V, VOL ≤ 0.1 V), and Ioff circuitry that disables outputs during power-down to prevent backflow current - critical for hot-swap and multi-rail system interoperability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2 V to 5.5 V - supports direct interfacing with 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Max Propagation Delay | 13 ns at 5 V - enables reliable operation up to 75 MHz fmax with 50 pF load, suitable for high-speed synchronous state machines. |
| Operating Temperature | –55°C to 125°C - qualified per JEDEC HAST, temperature cycling, and autoclave testing for space-grade reliability. |
| Ioff Support | Yes - prevents damaging current flow when VCC = 0 V, essential for partial-power-down sequencing in modular avionics systems. |
| Input Clamp Current | –20 mA - protects against transient overvoltage on inputs without external diodes in harsh ESD environments. |
| Output Drive Strength | ±12 mA at 5 V - sufficient to drive multiple CMOS loads or short PCB traces without buffering. |
| Latch-Up Immunity | >250 mA per JESD 17 - ensures robustness against supply transients and ground bounce in high-noise launch systems. |
Pinout & Package
Package: 14-pin TSSOP (PW), 5.0 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1CLR, 2CLR | Asynchronous Clear Input | Active-low reset: forces Q = L, Q̅ = H independently of clock; overrides all other inputs. |
| 1PRE, 2PRE | Asynchronous Preset Input | Active-low set: forces Q = H, Q̅ = L independently of clock; overrides all other inputs. |
| 1CLK, 2CLK | Clock Input | Positive-edge-triggered sampling point; data stable before tsu (3–7 ns) and after th (0.5–2.15 ns) required. |
| 1D, 2D | Data Input | Transfers to Q output on next valid CLK rising edge when PRE/CLR are inactive (high). |
| 1Q, 2Q | True Output | Non-inverted registered output; capable of sourcing/sinking ±12 mA at 5 V. |
| 1Q̅, 2Q̅ | Complement Output | Inverted registered output; provides complementary logic state for differential signaling or feedback paths. |
| VCC | Supply Voltage | Primary power rail (2–5.5 V); decoupling capacitor required within 10 mm for noise suppression. |
| GND | Ground Reference | Return path for all internal logic and I/O; must be low-impedance and tied to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent D flip-flops | Enables compact implementation of 2-bit registers, counters, or pipeline stages without external gating. |
| Extended temperature qualification | Validated for –55°C to 125°C operation via biased 85/85, HAST, and temperature cycling - meets MIL-PRF-38535 requirements. |
| Mixed-mode voltage operation | Allows 3.3 V inputs to safely drive 5 V outputs (and vice versa) without level-shifting circuitry. |
| Ioff partial-power-down protection | Prevents back-current flow when VCC is off, eliminating risk of damage during hot-insertion or staged power sequencing. |
| Low dynamic ground bounce | VOLP < 0.8 V at 3.3 V - reduces switching noise coupling into analog sections or adjacent signal lines. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV74AMPWREP | Same silicon die, identical electrical specs, but commercial temperature range (–40°C to 85°C) and non-qualified manufacturing pedigree. | Approved for industrial automation and test equipment; not rated for space or military use. | Select only if extended temperature and enhanced product qualification are not required. |
| SN74LV74A-Q1 | Automotive-qualified (AEC-Q100 Grade 1), same pinout and logic function, but optimized for 125°C ambient and automotive EMC profiles. | Designed for engine control units and ADAS domain controllers; lacks space-level radiation assurance documentation. | Choose for automotive safety-critical systems requiring ISO 26262 support, not for radiation-hardened deployment. |
Compared with SN74LV74AMPWREP and SN74LV74A-Q1, V62/06605-01XE uniquely delivers MIL-PRF-38535 Class V qualification, full radiation tolerance documentation, and guaranteed operation at –55°C - making it the sole option for flight-critical logic in launch vehicles and deep-space probes.

FAQ
What is the maximum clock frequency supported by V62/06605-01XE?
V62/06605-01XE supports up to 90 MHz maximum clock frequency at 3.3 V (CL = 50 pF) and 140 MHz at 5 V (CL = 50 pF), based on measured fmax values in the official datasheet. These limits assume proper layout, decoupling, and signal integrity - actual system-level frequency depends on board parasitics and load capacitance. The V62/06605-01XE datasheet specifies timing parameters including setup/hold windows and propagation delays that define the practical upper bound for reliable operation.
Does V62/06605-01XE support partial power-down mode?
Yes, V62/06605-01XE fully supports partial-power-down mode via its Ioff feature, which disables outputs when VCC = 0 V to prevent damaging current backflow. This capability is explicitly verified in the datasheet under "Recommended Operating Conditions" and "Electrical Characteristics", with Ioff specified at ≤5 µA across 0–5.5 V. The V62/06605-01XE is designed for use in systems with staged power sequencing, such as multi-rail avionics platforms.
What is the absolute maximum supply voltage rating for V62/06605-01XE?
The absolute maximum supply voltage (VCC) for V62/06605-01XE is 7 V, as stated in the "Absolute Maximum Ratings" table of the official datasheet. Operation beyond this limit risks permanent device damage. The recommended operating range remains 2 V to 5.5 V; exceeding 5.5 V voids functional guarantees even if below 7 V. All design margins for the V62/06605-01XE must respect this 7 V ceiling during transient events like ESD or power-rail overshoot.
Is V62/06605-01XE pin-compatible with standard SN74LV74A devices?
Yes, V62/06605-01XE is pin-compatible with SN74LV74A-family devices in the 14-pin TSSOP (PW) package, sharing identical pin numbering, functions, and footprint dimensions. The V62/06605-01XE uses the same PW package drawing (MO-153), land pattern, and stencil design as SN74LV74AMPWREP and SN74LV74A-Q1. However, due to its enhanced product qualification, V62/06605-01XE requires no PCB changes when replacing commercial variants in existing layouts.
What qualification standards apply to V62/06605-01XE?
V62/06605-01XE is qualified per MIL-PRF-38535 Class V requirements, including Highly Accelerated Stress Test (HAST), biased 85/85, temperature cycling, autoclave, electromigration, bond intermetallic life, and mold compound life testing. This pedigree is documented in the "Qualification Pedigree" section of the datasheet and confirmed in TI's Package Option Addendum. Unlike commercial or automotive variants, the V62/06605-01XE carries full military-grade reliability certification for space and defense applications.
