Texas Instruments TLV1393ID

Overview

TLV1393ID from Texas Instruments is a dual differential comparator IC designed for low-voltage, single-supply operation in precision threshold-detection circuits. It delivers 0.16 mA typical supply current, 0.65 µs response time at 5 V, rail-to-rail input common-mode range including ground, and operates from 2 V to 7 V - enabling use in battery-powered sensor interfaces and 3-V/5-V microcontroller systems.

For engineers reviewing the TLV1393ID datasheet, TLV1393ID pinout, TLV1393ID application, or TLV1393ID equivalent, key selection criteria include its low quiescent current, guaranteed operation down to 2 V, input offset voltage ≤9 mV over full temperature range, and SOIC-8 packaging compatible with standard surface-mount assembly processes.

Technical Context

The TLV1393ID implements two independent open-collector comparators using TI's proprietary low-voltage bipolar process. Each comparator features inputs that accept common-mode voltages from ground to VCC – 2 V and outputs capable of sinking ≥500 µA at 300 mV saturation under load.

It is fully specified across –40°C to 105°C and supports both 3-V and 5-V supply rails without performance degradation. Input bias current remains below –400 nA (full range), and input offset voltage is tightly controlled at ≤9 mV maximum over temperature - critical for stable hysteresis design and reference-level accuracy.

FAQ

What is the minimum supply voltage for reliable operation of TLV1393ID?

The TLV1393ID is fully specified and guaranteed to operate from 2 V to 7 V. At 2 V, input offset voltage remains ≤120 mV and response time degrades predictably per datasheet curves - making it suitable for deep-discharge battery monitoring where other comparators fail to function.

Does TLV1393ID support rail-to-rail input common-mode range?

Yes, TLV1393ID supports a common-mode input voltage range from 0 V (ground) to VCC – 2 V across the full temperature range. This allows direct connection of grounded-referenced sensors and eliminates the need for level-shifting circuitry in most 3-V and 5-V designs.

Can TLV1393ID outputs drive a 10-kΩ pull-up resistor to 5 V?

Yes - each TLV1393ID output can sink ≥500 µA while maintaining VOL ≤300 mV at 3 V supply and ≥600 µA at 5 V supply. With a 10-kΩ pull-up to 5 V, output low voltage remains well within TTL/CMOS logic thresholds, ensuring robust interfacing.

Is TLV1393ID pin-compatible with LM393?

No - although TLV1393ID shares the same SOIC-8 package and functional pinout (1OUT, 1IN–, 1IN+, GND, VCC, 2IN–, 2IN+, 2OUT), its electrical behavior differs significantly: lower supply current, faster response, tighter offset, and guaranteed 2-V operation. Layout reuse is possible, but electrical validation is required.

What is the maximum output sink current for TLV1393ID at 105°C?

At TA = 105°C and VCC = 5 V, TLV1393ID guarantees IOL ≥ 500 µA while maintaining VOL ≤ 300 mV. This is confirmed in the "Electrical Characteristics" table under full-range conditions - sufficient for driving LEDs, optocouplers, or logic inputs with standard pull-ups.
