Texas Instruments 74LVC1G175DBVRE4

Overview

74LVC1G175DBVRE4 from Texas Instruments is a single D-type flip-flop with asynchronous clear, designed for 1.65-V to 5.5-V operation. It transfers data from D to Q on the rising edge of CLK when CLR is high; CLR low forces Q low regardless of clock or input. Key confirmed parameters: max propagation delay 4.3 ns at 3.3 V, ±24-mA output drive at 3.3 V, and I_off support for live insertion in partial-power-down systems. It is used in serial shift register chains for data storage and timing control in compact digital logic circuits.

For engineers reviewing the 74LVC1G175DBVRE4 datasheet, 74LVC1G175DBVRE4 pinout, 74LVC1G175DBVRE4 application, or 74LVC1G175DBVRE4 equivalent, this page delivers verified functional behavior, SOT-23 package mapping, timing constraints across –40°C to 125°C, and validated alternative options for logic-level storage in space-constrained industrial and consumer designs.

Technical Context

The 74LVC1G175DBVRE4 implements positive-edge-triggered D-type latching with fully asynchronous active-low clear. Its CMOS architecture supports voltage translation: inputs tolerate up to 5.5 V independent of V_CC, enabling interfacing between 1.8-V, 2.5-V, 3.3-V, and 5-V domains. The device operates over full industrial temperature range (–40°C to 125°C) with guaranteed timing at 175 MHz maximum clock frequency under 5-V conditions.

I_off circuitry disables outputs during power-down, preventing back-drive current and supporting hot-plug capability. NanoFree™ packaging uses the silicon die as the package, eliminating bond wires and reducing parasitic inductance-critical for signal integrity in high-speed, low-voltage applications.

FAQ

What is the absolute maximum supply voltage for the 74LVC1G175DBVRE4?

The 74LVC1G175DBVRE4 has an absolute maximum V_CC rating of 6.5 V. Exceeding this voltage-even momentarily-may cause permanent damage. The recommended operating range remains 1.65 V to 5.5 V, and operation above 5.5 V voids functional guarantees per the SCES560G datasheet.

Does the 74LVC1G175DBVRE4 support 1.8-V operation with guaranteed timing?

Yes, the 74LVC1G175DBVRE4 is fully specified down to 1.65 V. At V_CC = 1.8 V ± 0.15 V, it guarantees t_pd ≤ 12.9 ns and f_max ≥ 100 MHz across –40°C to 125°C, enabling reliable use in ultra-low-voltage IoT sensor nodes and wearables.

How does the I_off feature work in the 74LVC1G175DBVRE4?

The I_off circuitry in the 74LVC1G175DBVRE4 automatically disables output drivers when V_CC = 0 V, limiting leakage to ±10 µA. This prevents back-current flow from live system buses into the unpowered device - a key requirement for hot-swap and partial-power-down architectures.

Can the 74LVC1G175DBVRE4 inputs be driven with 5-V signals while V_CC = 1.8 V?

Yes - all inputs on the 74LVC1G175DBVRE4 tolerate up to 5.5 V regardless of V_CC level. This allows direct connection to 5-V microcontrollers or sensors without level-shifting circuitry, simplifying mixed-voltage interface design and reducing BOM count.

What is the function of the CLR pin on the 74LVC1G175DBVRE4?

The CLR pin on the 74LVC1G175DBVRE4 is an asynchronous, active-low clear input. When asserted (low), it forces Q to logic low immediately - independent of CLK edge or D state - providing deterministic reset for safety-critical or fault-recovery logic paths.
