Texas Instruments TL3016IDRG4

Overview

TL3016IDRG4 from Texas Instruments is an ultrafast precision comparator with complementary TTL-compatible outputs, 7.6 ns typical propagation delay, ±5-V or single 5-V supply operation, and latch-enable capability for synchronized sampling in high-speed data acquisition systems.

For engineers reviewing the TL3016IDRG4 datasheet, TL3016IDRG4 pinout, TL3016IDRG4 application, or TL3016IDRG4 equivalent, this page delivers verified electrical specs, thermal performance across –40°C to 85°C, latch timing behavior, output drive strength, and functional substitution guidance against industry-standard comparators.

Technical Context

The TL3016IDRG4 employs a bipolar differential input stage with high open-loop gain (>97 dB CMRR) and low input offset voltage (≤3 mV over full temperature range), enabling precise threshold detection in noise-sensitive analog front-ends. Its complementary Q and Q̅ outputs support direct connection to TTL logic without level-shifting.

Latch enable functionality allows synchronous capture of comparator decisions under external control, with 2.5 ns setup time and rail-to-rail input common-mode range (–3.75 V to 3.5 V on ±5-V supplies). Propagation delay remains stable across load capacitance (0–50 pF) and supply voltage (±4.6 V to ±5.4 V).

FAQ

What is the maximum operating temperature range for TL3016IDRG4?

The TL3016IDRG4 is rated for continuous operation from –40°C to +85°C ambient temperature, validated per TI's production testing standards for the I-grade variant. This range supports deployment in automotive under-hood modules, industrial PLCs, and outdoor sensing equipment without derating. The device's thermal characteristics-including 12.5 mA max positive supply current at 85°C-are fully specified in the SLCS130D datasheet.

Does TL3016IDRG4 require dual supplies, or can it operate from a single 5-V rail?

TL3016IDRG4 supports both configurations: it operates from a single 5-V supply (with VCC– tied to GND) or dual ±5-V supplies. In single-supply mode, the input common-mode range is 1.25 V to 3.5 V; in dual-supply mode, it extends to –3.75 V to 3.5 V. Output swing remains TTL-compatible in both cases, with VOL ≤ 750 mV at 10 mA sink and VOH ≥ 3.4 V at 10 mA source.

How does the LATCH ENABLE function work on TL3016IDRG4?

The LATCH ENABLE pin (Pin 8) is an asynchronous, high-true control that freezes the Q and Q̅ outputs at their current logic states when driven high. A 2.5 ns setup time relative to the latch-enable assertion ensures deterministic capture of fast input transitions. When low, outputs respond immediately to input changes. No internal clock is used-the latch responds directly to the enable signal edge.

Is TL3016IDRG4 pin-compatible with LT1016?

Yes, TL3016IDRG4 is a pin-for-pin functional replacement for the LT1016 comparator in SOIC-8 packages. Both share identical pin assignments (VCC+, IN+, IN–, VCC–, Q OUT, Q̅ OUT, GND, LATCH ENABLE), enabling drop-in upgrades. However, TL3016IDRG4 adds latch-enable functionality not present in LT1016 and achieves 7.6 ns propagation delay versus LT1016's 10 ns-while consuming half the supply current.

What are the absolute maximum ratings for TL3016IDRG4 inputs and supplies?

Per the SLCS130D datasheet, TL3016IDRG4 has an absolute maximum supply voltage of –7 V to +7 V on VCC+ and VCC–, differential input voltage limit of ±7 V, input voltage range of –7 V to +7 V (including LATCH ENABLE), and output current limit of ±20 mA. Exceeding these values-even momentarily-may cause permanent damage. Recommended operating conditions constrain VCC to ±5 V and input common-mode range to –3.75 V to 3.5 V.
