Texas Instruments SN74LV175ADGVR

Overview

SN74LV175ADGVR from Texas Instruments is a quadruple positive-edge-triggered D-type flip-flop with asynchronous clear, designed for 2 V to 5.5 V operation. It features complementary Q and Q̅ outputs per stage, 7.5 ns maximum propagation delay at 5 V, Ioff support for partial-power-down mode, and mixed-mode voltage interface capability. It serves as a synchronous storage register in digital control logic, bus latching, and pattern generation circuits.

For engineers reviewing the SN74LV175ADGVR datasheet, SN74LV175ADGVR pinout, SN74LV175ADGVR application, or SN74LV175ADGVR equivalent, key selection criteria include its 16-pin TVSOP package, guaranteed tpd ≤ 7.5 ns at 5 V, direct CLR input timing (tw ≥ 5 ns), Ioff leakage < 5 µA at 0 V, and compatibility with 3.3 V/5 V mixed-signal systems.

Technical Context

The SN74LV175ADGVR implements four independent D-type latches synchronized to the rising edge of CLK, each with active-low asynchronous CLR. Its CMOS design enables rail-to-rail output swing and supports bidirectional voltage translation between 2.3 V and 5.5 V logic domains on all I/O pins.

It operates across –40°C to +85°C with guaranteed timing at VCC = 2.5 V, 3.3 V, and 5 V. The device includes robust noise immunity features: typical VOLP < 0.8 V and VOHV > 2.3 V at 3.3 V, and ESD ratings of ±2000 V HBM, ±200 V MM, and ±1000 V CDM.

FAQ

What is the maximum clock frequency supported by SN74LV175ADGVR?

The SN74LV175ADGVR supports up to 150 MHz maximum clock frequency at VCC = 5 V with CL = 15 pF, based on its 4 ns minimum setup time and 7.5 ns maximum propagation delay. At 3.3 V, fmax drops to 155 MHz under same load due to tighter timing margins. Real-world operation depends on PCB layout, termination, and load capacitance-TI recommends limiting CL to ≤50 pF for guaranteed performance across temperature.

Does SN74LV175ADGVR support partial-power-down mode?

Yes, SN74LV175ADGVR supports partial-power-down mode via its Ioff feature. When VCC = 0 V, the outputs are high-impedance and Ioff leakage remains below 5 µA, preventing damaging current flow between powered and unpowered sections of a system. This capability is explicitly characterized in TI's datasheet Section 6.5 and enables safe use in hot-swap and multi-rail power architectures.

What is the function of the complementary outputs (Q and Q̅) on SN74LV175ADGVR?

Each of the four flip-flops in SN74LV175ADGVR provides both true (Q) and inverted (Q̅) outputs, eliminating the need for external inverters in applications requiring both logic states-such as toggle configurations, differential signaling interfaces, or combinational logic reduction. This dual-rail output architecture reduces component count, PCB area, and signal path skew compared to single-output alternatives.

Can SN74LV175ADGVR interface directly with 5 V logic while operating at 3.3 V VCC?

Yes, SN74LV175ADGVR supports mixed-mode voltage operation: its inputs tolerate up to 5.5 V regardless of VCC level, allowing direct connection to 5 V buses while powered at 3.3 V. Output VOH/VOL remain referenced to the 3.3 V supply, ensuring compatibility with downstream 3.3 V receivers. This eliminates level-shifter components in bridging applications between legacy 5 V and modern low-voltage subsystems.

What is the recommended bypass capacitor for SN74LV175ADGVR?

Texas Instruments recommends a 0.1 µF ceramic capacitor placed physically adjacent to the VCC pin (Pin 16) and GND pin (Pin 8) of SN74LV175ADGVR. This minimizes high-frequency supply noise and stabilizes internal node voltages during switching transients. For systems with multiple power domains or high-speed clock distribution, paralleling a 1.0 µF capacitor improves low-frequency decoupling-layout guidelines emphasize shortest possible trace lengths and direct vias to ground plane.
