Product details
Overview
TLV3603MDBVREP from Texas Instruments is a radiation-hardened, high-speed comparator with rail-to-rail inputs, 2.5ns propagation delay, 325MHz toggle frequency, and adjustable hysteresis control-designed for pulse detection in satellite power systems and radar imaging payloads.
For engineers reviewing the TLV3603MDBVREP datasheet, TLV3603MDBVREP pinout, TLV3603MDBVREP application, or TLV3603MDBVREP equivalent, this device supports narrow-pulse (1.5ns) signal acquisition, latch-enabled output hold, and operation across –55°C to +125°C in space-grade SOT-23 packaging.
Technical Context
The TLV3603MDBVREP uses a high-speed complementary BiCMOS process to achieve sub-3ns propagation delay with low overdrive dispersion (700ps) and rail-to-rail input common-mode range extending 300mV beyond both supply rails. Its push-pull output drives CMOS logic directly without external pull-ups.
It operates from 2.4V to 5.5V supply, integrates Power-On Reset (VPOR = 2.1V), and supports two functional modes: active mode with resistor-programmed hysteresis (0–80mV) and latch mode triggered by LE/HYST pin voltage ≤400mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 2.5ns typical (low-to-high, 50mV overdrive) - enables precise timing capture of fast transient events |
| Toggle frequency | 325MHz - supports high-rate data sampling and clock recovery in radar/comm payloads |
| Input common-mode range | VEE – 0.3V to VCC + 0.3V - allows zero-crossing detection and maximizes dynamic range |
| Supply voltage range | 2.4V to 5.5V - compatible with 2.5V, 3.3V, and 5V system rails in avionics and space electronics |
| Operating temperature | –55°C to +125°C - qualified for extended-life space applications per V62/24633-01XE |
| Minimum pulse width | 1.5ns - detects narrow digital pulses in time-of-flight distance measurement systems |
| Hysteresis control | Adjustable via external resistor (0–1MΩ) or voltage (0.7–1.2V) on LE/HYST pin - suppresses noise-induced chatter |
Pinout & Package
TLV3603MDBVREP is housed in a 6-pin SOT-23 (DBV) package with nominal body size 1.25mm × 2.00mm and standard lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Push-pull output | Drives CMOS loads directly; no external pull-up required; sinks/sourses ≥10mA |
| VEE (Pin 2) | Negative supply | Ground reference for single-supply operation; supports rail-to-rail input below VEE |
| IN+ (Pin 3) | Non-inverting input | Accepts signals up to VEE – 0.3V and VCC + 0.3V; differential input impedance >67kΩ |
| IN− (Pin 4) | Inverting input | Paired with IN+ for differential comparison; matched offset drift ±3.0μV/°C |
| LE/HYST (Pin 5) | Latch enable / hysteresis control | Logic-low (≤400mV) enables latching; resistor-to-VEE sets hysteresis (0–80mV) |
| VCC (Pin 6) | Positive supply | 2.4V–5.5V operation; internal POR holds OUT low until VCC ≥ 2.1V |
Key Features
| Feature | Design Value |
|---|---|
| Radiation-hardened enhanced product | Qualified per V62/24633-01XE with controlled baseline, single fab/assembly site, and extended lifecycle |
| Adjustable hysteresis | 0–80mV programmable via external resistor or DAC voltage on LE/HYST pin - eliminates noise-induced oscillation |
| Output latch capability | Hold output state indefinitely when LE/HYST ≤ 400mV; tHOLD = 7.2ns, tSETUP = –1.4ns (internal trace compensation) |
| Low overdrive dispersion | 700ps variation across 10–125mV overdrive - ensures consistent timing regardless of input amplitude |
| ESD robustness | ±2000V HBM, ±1000V CDM - withstands handling and board-level ESD in cleanroom and flight environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH7322MKX/NOPB | 3.5ns propagation delay, differential LVDS output, no integrated hysteresis control | Requires external hysteresis network and level-shifting for single-ended logic interfacing | Preferred where differential signaling and higher noise immunity outweigh need for latch/hysteresis integration |
| ADCMP572BCPZ-REEL7 | 1.5ns propagation delay, 5.5GHz toggle frequency, fixed 10mV hysteresis, no latch function | Optimized for ultra-high-speed RF sampling but lacks programmable hysteresis and latch hold | Selected when absolute speed dominates and system-level hysteresis/latching is implemented externally |
Compared with LMH7322MKX/NOPB and ADCMP572BCPZ-REEL7, TLV3603MDBVREP uniquely combines space-qualified temperature range, on-chip latch, and resistor-programmable hysteresis in a cost-optimized SOT-23 package-reducing BOM count and layout complexity in radiation-tolerant systems.

FAQ
What is the guaranteed propagation delay specification for TLV3603MDBVREP across temperature?
The TLV3603MDBVREP has a maximum propagation delay of 4.5ns over the full –55°C to +125°C operating range, with typical performance at 2.5ns (low-to-high, 50mV overdrive). This value is assured by characterization and verified across all temperature extremes per the SNOSDK3 datasheet.
Does TLV3603MDBVREP support true rail-to-rail input operation?
Yes, TLV3603MDBVREP supports input common-mode voltage from VEE – 0.3V to VCC + 0.3V - enabling operation 300mV beyond both supply rails. This allows zero-crossing detection and full utilization of input dynamic range in single-supply configurations.
How is hysteresis programmed on TLV3603MDBVREP?
Hysteresis on TLV3603MDBVREP is programmed by connecting an external resistor between the LE/HYST pin and VEE. For example, a 150kΩ resistor yields ~30mV hysteresis at 5V supply. Alternatively, a DAC voltage (0.7–1.2V) applied to LE/HYST provides dynamic hysteresis control.
What happens to the output of TLV3603MDBVREP during power-up?
TLV3603MDBVREP includes an internal Power-On Reset (POR) circuit that holds the OUT pin low at VEE until VCC reaches 2.1V. Once VPOR threshold is exceeded, the comparator resumes normal operation and reflects input conditions - ensuring known startup behavior in avionics systems.
Can TLV3603MDBVREP drive capacitive loads above 5pF?
Yes, TLV3603MDBVREP can drive capacitive loads up to 100pF with minimal propagation delay increase (see Figure 5-33/34). However, larger loads (>50pF) may increase supply current and reduce slew rate; for optimal 2.5ns timing, keep load capacitance ≤10pF and minimize trace length.
