Product details
Overview
74LS175FP-E from Renesas Electronics is a quadruple positive-edge-triggered D-type flip-flop with asynchronous clear and complementary Q/Q̅ outputs, operating at 5 V supply, supporting up to 30 MHz clock frequency, with 16-pin SOP package (JEITA), used in synchronous logic control and data latching in industrial digital systems.
For engineers reviewing the 74LS175FP-E datasheet, 74LS175FP-E pinout, 74LS175FP-E application, or 74LS175FP-E equivalent, this page delivers verified timing parameters, TTL-compatible input thresholds, propagation delays (tPLH/tPHL ≤ 25 ns), absolute maximum ratings, and real-world use context for legacy TTL system upgrades and discrete logic design.
Technical Context
The 74LS175FP-E implements four independent D-type flip-flops sharing a common clock and asynchronous clear, each providing true and inverted outputs. It uses standard TTL circuitry with Schottky-clamped transistors for improved speed and noise immunity.
Its operation requires D-input setup time ≥20 ns and hold time ≥5 ns relative to the positive clock edge; clear pulse width must be ≥20 ns. Output drive capability is IOL = 8 mA (VOL ≤ 0.4 V) and IOH = –400 µA (VOH ≥ 2.7 V) under VCC = 4.75 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74LS (Low-power Schottky TTL), compatible with standard TTL voltage levels and drive requirements |
| Function | Quadruple D-type flip-flop with asynchronous clear and complementary Q/Q̅ outputs per stage |
| Max Clock Frequency | 30 MHz - supports high-speed synchronous state capture in legacy control logic |
| Propagation Delay | tPLH/tPHL ≤ 25 ns (CL = 15 pF, RL = 2 kΩ) - ensures predictable timing in cascaded register chains |
| Supply Voltage Range | VCC = 4.75–5.25 V - tight tolerance enables stable operation in regulated 5 V rails |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - robust noise margin against TTL-level signal degradation |
| Output Drive | IOL = 8 mA / IOH = –400 µA - sufficient to drive multiple LS-TTL inputs without buffering |
Pinout & Package
74LS175FP-E is housed in a 16-pin SOP package (JEITA standard FP-16DAV, Renesas code PRSP0016DH-B), measuring 10.06 mm × 5.5 mm × 1.75 mm, with Ni/Pd/Au-plated gull-wing leads and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Clear (Active-Low) | Asynchronous reset input shared across all four flip-flops; forces Q = L, Q̅ = H when low |
| 2–5, 9–12 | D1–D4 | Data inputs; sampled on rising clock edge and transferred to corresponding Q outputs |
| 3, 4, 10, 11 | Q1–Q4 | True outputs; reflect D-input state after positive clock transition |
| 6, 7, 13, 14 | Q̅1–Q̅4 | Inverted outputs; complement of Q outputs, enabling direct logic inversion without external gates |
| 8 | GND | Ground reference for all internal circuitry and I/O signals |
| 16 | VCC | +5 V power supply; must be decoupled locally to suppress switching noise |
| 15 | CLK | Common clock input; positive-edge-triggered; all flip-flops update simultaneously |
Key Features
| Feature | Design Value |
|---|---|
| Complementary Outputs | Each flip-flop provides both Q and Q̅ - eliminates need for external inverters in toggle or differential logic paths |
| Asynchronous Clear | Single-pin global reset - enables synchronized initialization of multi-bit registers without clock dependency |
| TTL-Compatible Interface | Meets standard LS-TTL VIH/VIL and IOL/IOH specs - interoperable with 74LS, 74S, and 74F families without level shifting |
| Low-Power Schottky Design | Typical ICC = 11 mA at VCC = 5.25 V - balances speed and power efficiency for board-level logic density |
| Industrial Temp Range | Operates from –20 °C to +75 °C - suitable for non-automotive industrial control cabinets and instrumentation |
Applications
| Parallel Data Latch | State Register Bank |
|---|---|
Use Scenario: Capturing 4-bit parallel sensor data (e.g., ADC output or switch bank status) into a stable register before microcontroller read. IC Role / Device Role / Timing Role: Synchronous latch holding sampled values until next clock cycle; clear resets all bits to zero on system startup. Use Value: Eliminates metastability risk by enforcing strict setup/hold timing and provides immediate Q/Q̅ access for dual-path logic evaluation. | Use Scenario: Storing intermediate states in a finite-state machine implemented with discrete TTL logic (e.g., traffic light controller). IC Role / Device Role / Timing Role: Four-bit state memory element updated on each clock edge; clear initializes to known start state (e.g., "red"). Use Value: Enables deterministic state transitions with guaranteed propagation delay ≤25 ns, critical for cycle-accurate FSM timing. |
| Shift Register Stage | Glitch-Free Control Signal Generator |
Use Scenario: Serving as one stage in a 4-bit serial-in/parallel-out shift register built from cascaded 74LS175FP-E units. IC Role / Device Role / Timing Role: Stores one bit of shifted data; Q output feeds next stage's D input; CLK advances all stages simultaneously. Use Value: Complementary outputs allow direct feedback for self-clocked or ring-counter configurations without added gates. | Use Scenario: Generating synchronized enable/disable pulses for analog multiplexers or power switches in test equipment. IC Role / Device Role / Timing Role: Latches control bits from slow microcontroller GPIO; Q/Q̅ outputs drive complementary gate drivers with matched timing. Use Value: Simultaneous Q and Q̅ edges minimize skew between paired control signals, preventing shoot-through in half-bridge drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LS175N | DIP-16 package (not surface-mount); identical electrical specs and pinout except physical form factor | Requires through-hole PCB layout; unsuitable for automated SMT assembly | Select when prototyping on breadboards or repairing legacy through-hole systems |
| 74HC175PW | CMOS family (74HC); higher noise immunity, wider VCC range (2–6 V), but different input thresholds and lower drive strength | Not TTL-compatible; requires level translation when interfacing with LS-TTL logic | Select only in new CMOS-based designs where power efficiency and rail flexibility outweigh TTL interoperability |
Compared with SN74LS175N, the 74LS175FP-E offers SMT compatibility and reduced board area; compared with 74HC175PW, it guarantees native TTL interface integrity and deterministic timing in mixed-logic legacy systems - making it the sole drop-in replacement for existing LS-TTL register implementations.

FAQ
What is the maximum operating temperature range for the 74LS175FP-E?
According to the Renesas HD74LS174/HD74LS175 datasheet Rev.3.00, the 74LS175FP-E is rated for operation from –20 °C to +75 °C. This industrial-grade temperature range supports deployment in enclosed control cabinets and non-automotive instrumentation environments. The 74LS175FP-E does not meet automotive or extended temperature specifications.
Does the 74LS175FP-E support true and inverted outputs on the same device?
Yes, the 74LS175FP-E provides complementary Q and Q̅ outputs for each of its four D-type flip-flops. Pins 3,4,10,11 deliver Q1–Q4, while pins 6,7,13,14 deliver Q̅1–Q̅4. This dual-output capability is intrinsic to the 74LS175FP-E design and eliminates the need for external inverters in applications requiring both logic polarities.
Is the 74LS175FP-E pin-compatible with other 74LS175 variants?
Yes, the 74LS175FP-E shares identical pinout and functionality with all HD74LS175 variants including HD74LS175P (DIP) and HD74LS175RPEL (JEDEC SOP). The FP suffix denotes JEITA-standard SOP packaging, but the 74LS175FP-E maintains full electrical and logical equivalence across the HD74LS175 family.
What is the minimum required setup time for D-inputs on the 74LS175FP-E?
The 74LS175FP-E requires a minimum D-input setup time (tsu) of 20 ns before the rising edge of the clock signal, as specified in the Recommended Operating Conditions table. This timing constraint must be met to ensure reliable data capture; violating it risks metastability or incorrect Q output states.
Can the 74LS175FP-E be used as a direct replacement for SN74LS175 in existing designs?
Yes, the 74LS175FP-E is functionally and electrically identical to Texas Instruments' SN74LS175, meeting the same 74LS logic family specifications for voltage thresholds, propagation delay, drive strength, and timing parameters. Its JEITA SOP package (FP-16DAV) allows direct substitution in SMT layouts originally designed for SN74LS175 variants with matching footprint.
