Texas Instruments TL3016CD

Overview

TL3016CD from Texas Instruments is an ultrafast precision comparator IC operating from single 5-V or dual ±5-V supplies, delivering 7.6 ns typical propagation delay, 10.6 mA typical positive supply current, and ±20 mA output drive capability with complementary TTL-compatible outputs and latch-enable functionality. It serves in high-speed analog-to-digital interface circuits, pulse-width modulation feedback loops, and overvoltage protection systems.

For engineers reviewing the TL3016CD datasheet, TL3016CD pinout, TL3016CD application, or TL3016CD equivalent, key selection considerations include propagation delay vs. supply current trade-off, latch-enable timing (2.5 ns setup), input offset voltage (0.5–3 mV), and SOIC-8 thermal performance (725 mW at 25°C).

Technical Context

The TL3016CD employs a bipolar differential input stage with high-gain amplification and emitter-coupled logic (ECL)-derived output latching, enabling sub-10 ns propagation while maintaining precision offset (≤3 mV over 0°C to 70°C). Its complementary Q and Q̅ outputs support direct TTL interfacing without level-shifting.

LATCH ENABLE operates with 0.8 V low-level and 2 V high-level thresholds, requiring 2.5 ns setup time relative to input transition. The device supports rail-to-rail common-mode input range (–3.75 V to +3.5 V on ±5 V supplies) and exhibits 80–97 dB CMRR and 60–100 dB supply rejection across supply rails.

FAQ

What is the maximum operating temperature range for the TL3016CD?

The TL3016CD is rated for operation from 0°C to 70°C ambient temperature, as confirmed by its "C" grade designation and the "TL3016CD" ordering suffix in TI's packaging addendum. This commercial-grade temperature range aligns with its SOIC-8 package thermal rating and electrical specifications tested across this interval, including input offset voltage (≤3.5 mV) and propagation delay (≤11.2 ns).

Does the TL3016CD support single-supply operation?

Yes, the TL3016CD supports true single-supply operation from +5 V only, with specified common-mode input range of 1.25 V to 3.5 V under that condition. Its complementary outputs remain TTL-compatible, and all key parameters-including 7.6 ns propagation delay and 10.6 mA supply current-are guaranteed under single +5 V bias per the SLCS130D datasheet Section 4.

How does the LATCH ENABLE pin function on the TL3016CD?

The LATCH ENABLE pin on the TL3016CD controls output transparency: when high (≥2 V), Q and Q̅ follow input transitions; when low (≤0.8 V), outputs retain their last state. It requires 2.5 ns setup time before input edge, draws 24–39 µA at VIH, and enables glitch-free state capture in timing-critical applications like digital oscilloscope trigger circuits.

Is the TL3016CD pin-compatible with the LT1016?

Yes, the TL3016CD is explicitly documented as a pin-for-pin functional replacement for the LT1016 comparator, sharing identical SOIC-8 pinout, terminal functions, and footprint. However, TL3016CD improves propagation delay (7.6 ns vs. 10 ns) and reduces supply current (10.6 mA vs. 22 mA), making it a drop-in upgrade where higher speed and lower power are needed.

What is the output drive capability of the TL3016CD?

The TL3016CD provides ±20 mA output current capability per output (Q and Q̅), with VOL = 600 mV at 4 mA sink and VOH = 3.6 V at 1 mA source under ±5 V supplies. This allows direct driving of TTL loads, 50 Ω transmission lines, or parallel inputs without external buffers-verified across the full 0°C to 70°C operating range.
