Product details
Overview
D15LD74ANP#T0P from Renesas Electronics is an 8-bit D-type flip-flop driver with open-drain NMOS outputs, common clock and clear inputs, and 15 V drain-source voltage tolerance. It operates from 3.0–5.5 V supply, delivers up to 200 mA per output, and supports industrial temperature range (–20 to +85 °C). It is used in amusement equipment for driving LED arrays or solenoid loads.
For engineers reviewing the D15LD74ANP#T0P datasheet, D15LD74ANP#T0P pinout, D15LD74ANP#T0P application, or D15LD74ANP#T0P equivalent, key selection criteria include open-drain output capability, simultaneous multi-channel switching, Schmitt-trigger input hysteresis, and DILP-20 package compatibility with through-hole PCB assembly.
Technical Context
This device integrates eight independent D-type latches with edge-triggered clocking on the rising edge and asynchronous active-low clear. Each output uses a high-voltage NMOS transistor rated for 15 V VDS, enabling direct interface with external loads such as LEDs, relays, or small motors without external level-shifting.
All inputs feature Schmitt-trigger circuitry (VH = 1.5 V typ), ensuring noise immunity and stable logic transitions across varying signal rise/fall times. The device maintains low quiescent current (≤5 µA) and input leakage (≤1 µA), supporting power-sensitive control applications where standby integrity matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output type | Open-drain NMOS - enables wired-OR logic, level translation, and direct drive of external 12 V loads |
| VDS(max) | 15 V - supports operation with 12 V rail loads without external flyback protection |
| IDS(max) per channel | 200 mA - sufficient for driving high-brightness LEDs or miniature solenoids |

Applications
| LED Display Driver | Amusement Equipment Control |
|---|---|
|
Use Scenario: Driving 8-segment alphanumeric displays or dot-matrix panels in arcade cabinets using 12 V common-anode LEDs. IC Role / Device Role / Timing Role: Acts as a parallel-output sink driver; receives latched data from MCU and clocks all segments simultaneously via shared CLK. Use Value: Eliminates need for eight discrete MOSFETs; 200 mA per channel supports high-brightness segments; Schmitt inputs tolerate noisy cabinet wiring. |
Use Scenario: Controlling solenoid-based prize dispensers, coin acceptor indicators, and sound effect triggers in coin-operated games. IC Role / Device Role / Timing Role: Provides isolated, high-current sinking paths for electromechanical actuators under MCU GPIO supervision. Use Value: 15 V VDS rating matches standard 12 V solenoid supplies; common CLR enables emergency shutdown of all actuators. |
| Industrial Panel Indicator | Legacy System Interface |
|
Use Scenario: Replacing aging discrete driver ICs in factory HMI panels requiring 8-channel status indication with 12 V incandescent or LED lamps. IC Role / Device Role / Timing Role: Serves as drop-in replacement for obsolete 74LS/HC-series drivers with enhanced voltage and current capability. Use Value: DILP-20 footprint matches legacy layouts; 3.0–5.5 V supply simplifies integration with modern 3.3 V controllers. |
Use Scenario: Interfacing microcontrollers to legacy 12 V logic systems (e.g., older PLC I/O modules or test equipment backplanes). IC Role / Device Role / Timing Role: Translates low-voltage digital outputs to 12 V-compatible sinking signals while preserving timing integrity. Use Value: Propagation delay ≤65 ns ensures compatibility with 10 MHz+ control buses; open-drain outputs prevent bus contention. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit open-drain driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB62706CFNG | 16-channel, 50 V VDS, SPI serial interface, no internal clock/clear logic | Requires external shift register control; better suited for space-constrained designs needing higher channel count | Select when board area is limited and serial configuration is acceptable; not pin-compatible |
| ULN2803ADWR | 8-channel Darlington array, 50 V VCE, 500 mA per channel, TTL-compatible inputs, no clocking logic | Lacks flip-flop functionality; outputs follow inputs directly - unsuitable for synchronous update or latch-hold requirements | Choose only for simple DC load switching without timing control; requires external latch if synchronization needed |
Compared with TB62706CFNG and ULN2803ADWR, D15LD74ANP#T0P uniquely combines synchronous 8-bit latching, Schmitt-trigger inputs, and 15 V open-drain outputs in a through-hole DILP package - making it optimal for legacy-compatible, noise-immune, and timing-critical amusement equipment designs.

FAQ
What is the maximum continuous output current per channel for D15LD74ANP#T0P?
D15LD74ANP#T0P supports up to 200 mA per output channel when operated within its specified duty cycle limits (e.g., ≤60% for SDIP/DILP packages at 25°C). Derating applies at elevated temperatures and higher simultaneous channel counts - full 200 mA per channel is guaranteed only with ≤55% duty cycle at 85°C per the datasheet's application curves.
Does D15LD74ANP#T0P require external pull-up resistors on its Y0–Y7 outputs?
Yes, D15LD74ANP#T0P features open-drain NMOS outputs and requires external pull-up resistors to define the high-level voltage and sink current path. The value depends on load voltage and speed requirements - typical values range from 1–10 kΩ for 12 V LED loads, selected to ensure VOL ≤ 0.77 V at 200 mA sink current.
Can D15LD74ANP#T0P be used with a 3.3 V microcontroller without level shifting?
Yes, D15LD74ANP#T0P accepts 3.3 V logic inputs directly: VIH(min) = VCC × 0.76 = 2.51 V at 3.3 V supply, and VIL(max) = VCC × 0.24 = 0.79 V - well within standard 3.3 V CMOS logic thresholds. Its Schmitt-trigger inputs further enhance noise margin for robust interfacing.
What is the function of the CLR pin on D15LD74ANP#T0P?
The CLR (Clear) pin on D15LD74ANP#T0P is an active-low asynchronous input that forces all eight Y outputs into high-impedance (open) state regardless of clock or data inputs. This provides immediate, hardware-level disablement of all loads - essential for safety interlocks or emergency stop functions in amusement equipment.
Is D15LD74ANP#T0P RoHS compliant?
Yes, D15LD74ANP#T0P uses Ni/Pd/Au surface treatment (per ordering code "0") and complies with EU RoHS Directive requirements. Renesas confirms environmental compliance for this part in its official documentation and product change notices.
