Analog Devices Inc. LT1713IMS8#TRPBF

Overview

LT1713IMS8#TRPBF from Analog Devices (formerly Linear Technology) is a single, ultrafast 7ns rail-to-rail input/output comparator with internal TTL/CMOS-compatible latch, optimized for 2.4V–12V single or ±2.4V–±6V dual supplies. It delivers 5mA supply current per comparator, 0.5–3ns differential propagation delay, and rail-to-rail complementary outputs capable of sinking 10mA to within 0.5V of GND or sourcing 10mA to within 0.7V of V+. It is used in high-speed crystal oscillator circuits, pulse width modulators, and fast A/D converter front-ends.

For engineers reviewing the LT1713IMS8#TRPBF datasheet, LT1713IMS8#TRPBF pinout, LT1713IMS8#TRPBF application, or LT1713IMS8#TRPBF equivalent, key selection criteria include propagation delay at low overdrive (8.5ns at 5mV), latch enable hysteresis (≈100mV), input common-mode range extending 100mV beyond rails, output drive capability under load, and MSOP-8 thermal performance (θ_JA = 250°C/W).

Technical Context

The LT1713IMS8#TRPBF employs a rail-to-rail differential input stage composed of complementary NPN/PNP pairs, enabling operation with inputs up to 100mV beyond either supply rail without phase reversal. Its matched complementary outputs are internally latched via a dedicated LATCH ENABLE pin with built-in 100mV hysteresis to reject slow or noisy control signals.

Propagation delay is specified with 10pF load and 1kΩ test load referenced to mid-supply (single supply) or ground (dual supply). The latch function holds output state as long as the LATCH ENABLE pin remains high, with 8ns latch propagation delay, 1.5ns setup time, and zero hold time - enabling precise timing capture in high-speed sampling systems.

Key Specifications

Pinout & Package

LT1713IMS8#TRPBF is housed in an 8-lead plastic MSOP package (3.0mm × 3.0mm × 0.86mm), rated for θ_JA = 250°C/W, with exposed pad not electrically connected. Pin 1 is V+, pin 6 is GND, and pin 5 is LATCH ENABLE - all pins are surface-mount compatible with standard reflow profiles.

The LT1713IMS8#TRPBF belongs to Linear's UltraFast™ comparator family, designed specifically for high-speed timing-critical applications such as ATE, switching regulator control, and precision oscillator circuits where sub-10ns decision latency and rail-to-rail interface capability are essential.

FAQ

What is the maximum supply voltage rating for LT1713IMS8#TRPBF?

The LT1713IMS8#TRPBF has an absolute maximum positive-to-negative supply voltage of 12.6V. When operated on single supply, V+ to GND must not exceed 12.6V; for dual supply, V+ to V– must not exceed 12.6V, and V– must remain between –7V and 0V. Exceeding these limits risks permanent damage to the LT1713IMS8#TRPBF die.

Does LT1713IMS8#TRPBF support true rail-to-rail input operation?

Yes, the LT1713IMS8#TRPBF supports rail-to-rail input operation with a common-mode range extending 100mV beyond both supply rails - i.e., from –0.1V to V+ + 0.1V on single supply, or –5.1V to +5.1V on ±5V supplies. This is verified across –40°C to +85°C and enables direct interfacing with sensors and DACs operating at supply extremes.

How does the internal latch in LT1713IMS8#TRPBF behave during power-up?

During power-up, the LT1713IMS8#TRPBF latch defaults to transparent (flow-through) mode because the LATCH ENABLE pin floats low when unconnected. To ensure predictable startup behavior, tie LATCH ENABLE to GND for immediate transparency or to a controlled logic signal. The LT1713IMS8#TRPBF latch only captures and holds data when LATCH ENABLE is actively driven high.

Can LT1713IMS8#TRPBF drive 50Ω transmission lines directly?

No, the LT1713IMS8#TRPBF is not designed for direct 50Ω line driving. Its outputs are optimized for CMOS/TTL loading (≤10mA into resistive loads). For 50Ω transmission lines, use a dedicated high-speed buffer (e.g., LTC681) or add series termination. Driving 50Ω loads directly may cause excessive current draw, timing distortion, and degraded jitter performance in the LT1713IMS8#TRPBF.

What is the guaranteed propagation delay specification for LT1713IMS8#TRPBF over temperature?

The LT1713IMS8#TRPBF guarantees a maximum propagation delay of 12.5ns over the full –40°C to +85°C industrial temperature range, measured at 20mV overdrive with 10pF load and 1kΩ test load. At 25°C, typical delay is 7ns; at 5mV overdrive, typical delay is 8.5ns - both values are characterized but not fully guaranteed across temperature.
