Texas Instruments V62/24609-01XE

Overview

V62/24609-01XE from Texas Instruments is an enhanced-product dual D-type positive-edge-triggered flip-flop with integrated voltage-level translation, asynchronous preset/clear, and 5.5-V tolerant inputs. It operates from 1.6 V to 5.5 V supply, supports up/down translation (e.g., 1.2 V → 1.8 V, 3.3 V → 2.5 V), delivers ≤12.8 ns propagation delay at 5 V, and is qualified for defense, aerospace, and medical systems per controlled baseline and extended life-cycle requirements.

For engineers reviewing the V62/24609-01XE datasheet, V62/24609-01XE pinout, V62/24609-01XE application, or V62/24609-01XE equivalent, this page provides verified functional identity, TSSOP-14 pin mapping, translation capability boundaries, timing specifications across 1.8–5 V supplies, and validated alternatives for radiation-tolerant logic interface design.

Technical Context

The V62/24609-01XE implements two independent CMOS D-flip-flops with asynchronous active-low PRE/CLR, rising-edge CLK triggering, and LVxT input architecture enabling bidirectional level translation. Its input threshold is reduced to support low-voltage up-translation (e.g., 1.2 V input with 1.8 V VCC), while 5.5-V tolerant pins enable down-translation without external circuitry.

Each channel features balanced push-pull outputs referenced to VCC, with VOH ≥ VCC − 0.1 V (IOH = −50 µA) and VOL ≤ 0.1 V (IOL = 50 µA). Latch-up immunity exceeds 250 mA per JESD17, and operation is guaranteed from −55 °C to +125 °C under military-grade screening.

FAQ

What is the maximum clock frequency supported by V62/24609-01XE at 3.3 V supply?

V62/24609-01XE supports a maximum clock frequency of 56.7 MHz at 3.3 V with 15 pF load capacitance, as specified in the Switching Characteristics table. This value is derived from tPLH/tPHL propagation delays of 6.1 ns/6.8 ns (typical) and accounts for setup/hold timing margins. The device maintains full functionality across its entire −55 °C to +125 °C operating range.

Does V62/24609-01XE support down-translation from 5 V to 1.8 V?

Yes, V62/24609-01XE supports down-translation from 5 V inputs to 1.8 V outputs when operated with VCC = 1.8 V. Its 5.5-V tolerant inputs accept 5 V signals directly, and output levels are referenced to VCC, producing valid 1.8 V CMOS logic levels. This configuration is explicitly listed in the LVxT Enhanced Input Voltage section of the datasheet.

How does the asynchronous preset/clear function behave in V62/24609-01XE?

In V62/24609-01XE, the active-low PRE and CLR inputs operate asynchronously-asserting either immediately forces Q to HIGH or LOW, respectively, regardless of CLK state or timing. These functions override all synchronous operations and remain effective across the full −55 °C to +125 °C temperature range, making them ideal for system-wide reset or initialization in safety-critical applications.

Is V62/24609-01XE pin-compatible with standard SN74LV2T74 devices?

V62/24609-01XE uses the identical PW (TSSOP-14) package and pinout as the commercial SN74LV2T74, including identical terminal assignments for PRE, CLR, CLK, D, Q, Q, GND, and VCC. However, V62/24609-01XE incorporates enhanced product controls (controlled baseline, extended testing) not present in commercial variants-ensuring mechanical and electrical compatibility without layout changes.

What thermal derating applies to V62/24609-01XE at 125 °C ambient?

V62/24609-01XE has a junction-to-ambient thermal resistance (RθJA) of 147.7 °C/W in the PW package. At 125 °C ambient and 5.5 V supply, maximum power dissipation must be limited to ensure junction temperature remains below 150 °C. With typical ICC = 20 µA and output loading ≤ ±15 mA, self-heating is negligible-no external heatsinking is required for standard operation within datasheet limits.
