Texas Instruments SN74LVC112ADGVRG4

Overview

SN74LVC112ADGVRG4 from Texas Instruments is a dual negative-edge-triggered J-K flip-flop with independent preset and clear inputs, designed for 1.65V–3.6V V_CC operation. It delivers 4.8ns max propagation delay at 3.3V, supports 5.5V-tolerant inputs, and operates across –40°C to +125°C - enabling use in high-speed bus interface and data latching circuits within industrial servers and network switches.

For engineers reviewing the SN74LVC112ADGVRG4 datasheet, SN74LVC112ADGVRG4 pinout, SN74LVC112ADGVRG4 application, or SN74LVC112ADGVRG4 equivalent, key selection criteria include its dual J-K architecture with asynchronous preset/clear, 16-pin TVSOP (DGV) package, 150MHz max clock frequency, and I_OFF protection for partial-power-down systems.

Technical Context

This device implements two independent, negative-edge-triggered J-K flip-flops sharing no internal logic coupling. Each section features asynchronous active-low preset (PRE) and clear (CLR) inputs that override clocked J/K behavior, allowing immediate output forcing regardless of clock state or input levels.

Its CMOS design supports mixed-voltage interfacing: inputs tolerate up to 5.5V while operating from 1.65V–3.6V V_CC, and the I_OFF feature disables current flow when V_CC = 0V - critical for hot-swap and power-gating applications where signal integrity must be maintained during supply sequencing.

FAQ

What is the maximum clock frequency supported by the SN74LVC112ADGVRG4?

The SN74LVC112ADGVRG4 supports a maximum clock frequency of 150MHz at V_CC = 3.3V and operating temperatures from –40°C to +85°C. At the extended range (–40°C to +125°C), the guaranteed f_max remains 150MHz for V_CC ≥ 2.7V, per TI's switching characteristics tables. This makes SN74LVC112ADGVRG4 suitable for high-speed synchronous logic in networking and computing infrastructure.

Does the SN74LVC112ADGVRG4 support 5V input signals?

Yes, the SN74LVC112ADGVRG4 accepts input voltages up to 5.5V regardless of V_CC level - a key feature documented in its "Features" and "Recommended Operating Conditions" sections. This 5V tolerance allows direct interfacing with legacy 5V logic without external level shifters, simplifying mixed-voltage system design while maintaining SN74LVC112ADGVRG4 reliability and signal integrity.

What is the purpose of the I_OFF feature in the SN74LVC112ADGVRG4?

The I_OFF feature in SN74LVC112ADGVRG4 disables current flow through inputs and outputs when V_CC = 0V, preventing unintended back-driving of powered rails during partial power-down or hot-swap events. This behavior is explicitly specified in TI's Feature Description and ensures safe operation in multi-rail systems - a critical requirement not present in standard LVC devices and directly enabled in SN74LVC112ADGVRG4.

Can the SN74LVC112ADGVRG4 be used as a toggle flip-flop?

Yes, the SN74LVC112ADGVRG4 can function as a toggle flip-flop by connecting both J and K inputs high on either section. On each negative clock edge, the Q output will invert - producing a clean divide-by-2 clock output. This mode is confirmed in TI's Device Functional Modes table and is widely used in clock division, frequency synthesis, and simple counter designs leveraging SN74LVC112ADGVRG4's dual independent sections.

What package type is used for the SN74LVC112ADGVRG4?

The SN74LVC112ADGVRG4 uses a 16-pin Thin Very Small Outline Package (TVSOP), designated as DGV. Its dimensions are 3.6mm × 6.4mm with 0.5mm lead pitch, and it carries an MSL-1 rating for peak reflow at 260°C. This compact, surface-mount package is optimized for high-density PCB layouts in space-constrained applications such as network switches and embedded controllers using SN74LVC112ADGVRG4.
