Texas Instruments TLV3501AIDBVR

Overview

TLV3501AIDBVR from Texas Instruments is a single, rail-to-rail input/output, 4.5-ns high-speed comparator in 6-pin SOT-23 package, operating from 2.7 V to 5.5 V supply, featuring shutdown control, 6 mV internal hysteresis, and push-pull CMOS output-used for precision threshold detection in automatic test equipment and wireless base station timing circuits.

For engineers reviewing the TLV3501AIDBVR datasheet, TLV3501AIDBVR pinout, TLV3501AIDBVR application, or TLV3501AIDBVR equivalent, key selection considerations include propagation delay vs. overdrive voltage (4.5 ns at 100 mV), shutdown turn-on time (100 ns), rail-to-rail common-mode range (extends 0.2 V beyond rails), and SOT-23 thermal resistance (192.2°C/W).

Technical Context

The TLV3501AIDBVR implements a high-gain, low-offset comparator core with internal hysteresis (6 mV) and ESD-protected inputs that tolerate ±0.3 V beyond supply rails. Its push-pull CMOS output drives TTL/CMOS loads directly without external pull-ups.

Shutdown functionality is controlled by a dedicated SHDN pin: pulled low enables operation (3.2 mA quiescent current); pulled high disables the comparator and reduces current to 2 µA while placing OUT in high-impedance state-critical for power-gated signal chains in portable instrumentation.

FAQ

What is the maximum toggle frequency supported by TLV3501AIDBVR?

The TLV3501AIDBVR supports a maximum toggle frequency of 80 MHz under specified conditions (50-mV overdrive, 5-V supply). This is derived from its 4.5-ns propagation delay and 1.5-ns rise/fall times, enabling reliable operation in high-speed clock monitoring and pulse-width discrimination circuits. Actual achievable frequency depends on layout, load capacitance, and overdrive level.

Does TLV3501AIDBVR require external pull-up resistors on its output?

No, TLV3501AIDBVR does not require external pull-up resistors because it features a push-pull CMOS output stage. The output actively drives high and low states rail-to-rail, delivering 30 mV max voltage drop at ±1 mA load. This eliminates bus contention risks and simplifies interface design with TTL or CMOS logic families.

How does the shutdown function behave on TLV3501AIDBVR?

When the SHDN pin is driven above (V+) − 0.9 V, TLV3501AIDBVR enters shutdown mode: quiescent current drops to 2 µA and the OUT pin goes to high-impedance state. When SHDN falls below (V+) − 1.7 V, the device wakes up in 100 ns and resumes normal operation with 3.2 mA supply current. Unused SHDN must be tied to V−.

Can TLV3501AIDBVR operate from a 2.5-V supply?

No, TLV3501AIDBVR is not specified for 2.5-V operation. Its recommended operating supply range is 2.7 V to 5.5 V. At 2.5 V, the device may power up but performance-including propagation delay, output swing, and hysteresis-is not guaranteed. For 2.5-V systems, consider alternatives like TLV3604 or LMH7322 with lower VCC minima.

What is the input common-mode voltage range for TLV3501AIDBVR?

The input common-mode voltage range for TLV3501AIDBVR is (V−) − 0.2 V to (V+) − 0.2 V. This "beyond-the-rails" capability allows the device to accept input signals slightly below ground or above V+, making it ideal for level-shifting, AC-coupled signal detection, and single-supply applications where references extend outside the supply domain.
