Texas Instruments TLV2393IPWLE

Overview

TLV2393IPWLE from Texas Instruments is a dual differential comparator IC designed for low-voltage, single-supply operation in precision threshold detection circuits. It delivers 450 ns typical response time at 3 V, supports supply voltages from 2 V to 7 V, features rail-to-rail input common-mode range including ground, and operates across –40°C to 105°C for industrial sensing and power management applications.

For engineers reviewing the TLV2393IPWLE datasheet, TLV2393IPWLE pinout, TLV2393IPWLE application, or TLV2393IPWLE equivalent, this device is selected for high-speed, low-power analog decision-making where fast settling, ground-sensing capability, and TSSOP-8 packaging are critical - especially in battery-powered instrumentation and 3-V/5-V system upgrades replacing LM393.

Technical Context

The TLV2393IPWLE employs a proprietary Texas Instruments low-voltage, high-speed bipolar process optimized for speed-power trade-offs in comparator applications. Its architecture enables sub-microsecond propagation delay while maintaining stable operation with inputs extending to GND and outputs capable of sourcing/sinking up to 4 mA (low-side) or 100 nA (high-side).

It is fully specified at both 3 V and 5 V supplies, with input offset voltage ≤5 mV (typ), input bias current ≤–250 nA (typ), and output stage compatible with open-collector loads - requiring external pull-up for logic-level compatibility. The device does not include internal hysteresis or reference, necessitating external configuration for noise-immune thresholding.

FAQ

What is the maximum operating supply voltage for TLV2393IPWLE?

The TLV2393IPWLE has an absolute maximum supply voltage of 7 V. Operation beyond this rating risks permanent damage. For reliable long-term use, TI specifies recommended operation between 2 V and 7 V, with full electrical characterization validated at both 3 V and 5 V supplies. The TLV2393IPWLE maintains stable performance across this range without derating.

Does TLV2393IPWLE support input voltages down to ground?

Yes, the TLV2393IPWLE supports a common-mode input voltage range that includes ground (0 V) across its full operating temperature range (–40°C to 105°C). At 3 V supply, the minimum common-mode voltage is 0 V, enabling direct interfacing with ground-referenced signals such as battery terminals or current-sense amplifier outputs - a key advantage over older comparators like LM393.

What is the typical propagation delay of TLV2393IPWLE at 3 V supply?

The TLV2393IPWLE exhibits a typical propagation delay of 450 ns at 3 V supply, measured with a 100-mV input step and 5-mV overdrive into a 15 pF load. This value is confirmed in the official TI datasheet SLCS121A (Rev. April 1994), page 10, under switching characteristics. The TLV2393IPWLE achieves this speed while consuming only 1.1 mA quiescent current - a key differentiator in low-power, high-speed applications.

Is TLV2393IPWLE pin-compatible with LM393?

No, TLV2393IPWLE is not pin-compatible with LM393. While both are dual comparators in 8-pin packages, the TLV2393IPWLE uses TSSOP-8 (PW) packaging with 0.65 mm pitch, whereas standard LM393 variants use SOIC-8 (D) or PDIP-8 (P) with 1.27 mm pitch. Pin functions differ: TLV2393IPWLE places GND on pin 4 and VCC on pin 5, while LM393 places VCC on pin 8 and GND on pin 4 - requiring PCB redesign for substitution.

What output configuration does TLV2393IPWLE use?

The TLV2393IPWLE features open-collector outputs on both channels (pins 1 and 6). Each output requires an external pull-up resistor to VCC or another logic rail to generate a defined high state. This configuration allows wired-OR logic, level translation, and flexible interfacing with TTL, CMOS, or microcontroller GPIO pins - but prohibits direct push-pull driving without additional circuitry.
