Product details
Overview
TBD62789APG from Toshiba is an 8-channel source-type DMOS transistor array with integrated D-type flip-flop logic, designed for high-voltage digital output driving in industrial control and relay replacement applications. It delivers up to 50 V output voltage, 500 mA per channel peak current, and operates across –40°C to +85°C ambient temperature.
For engineers reviewing the TBD62789APG datasheet, TBD62789APG pinout, TBD62789APG application, or TBD62789APG equivalent, key selection considerations include its 20-pin DIP package, synchronous clocked latch behavior, clamp diode protection per channel, thermal derating requirements, and absence of internal overcurrent protection.
Technical Context
The TBD62789APG integrates eight independent DMOS source drivers with edge-triggered D-type flip-flops, enabling synchronized latching of 8-bit parallel data on CLK rising edge. Each channel features a built-in clamp diode rated for 50 V reverse voltage and 400 mA forward current, supporting inductive load switching.
It operates with a single 4.5–50 V supply (VDD), accepts TTL/CMOS-compatible input levels (0–0.8 V for OFF, 2.0–5.5 V for ON), and exhibits propagation delays ≤200 ns (CL = 15 pF, RL = 25 Ω). The /CLR pin provides asynchronous reset capability across all channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Max | 50 V - supports direct driving of solenoids, relays, and lamps without external level-shifting |
| Output Current Max (per ch) | 500 mA - enables direct interface with medium-power loads; derated to 400 mA at Ta = 25°C, 195 mA at Ta = 85°C (8-ch ON, 50% duty) |
| Input Logic Compatibility | TTL/CMOS - accepts 0–0.8 V (OFF) and 2.0–5.5 V (ON) inputs, compatible with standard microcontroller GPIOs |
| Propagation Delay | ≤200 ns - ensures deterministic timing in synchronous control systems with 5 MHz max clock frequency |
| On-Resistance (Typ) | 0.49 Ω @ IOUT = −350 mA, VDD = 10 V - limits conduction loss and self-heating under sustained load |
| Clamp Diode Rating | 50 V VR, 400 mA IF - provides integrated flyback protection for inductive loads without external diodes |
| Power Dissipation (PCB) | 1.76 W - requires thermal design on 50 × 50 mm PCB (40% Cu); derates 14.1 mW/°C above 25°C |
Pinout & Package
Package: DIP20-P-300-2.54A (20-pin dual in-line, 300 mil body width, 2.54 mm pitch, typical weight 1.4 g).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CLR | Asynchronous clear input | Active-low global reset: forces all Y outputs to high-impedance (OFF) regardless of CLK or D states |
| CLK | Clock input | Rising-edge triggered: latches D1–D8 data into internal flip-flops and updates Y1–Y8 outputs synchronously |
| D1–D8 | Data inputs | Parallel 8-bit input bus; each controls corresponding Y output via D-type latch behavior |
| GND | Ground reference | Common return path for logic and power; must be low-impedance to minimize noise coupling |
| Y1–Y8 | Source-type DMOS outputs | High-side switches: sink current from load to GND when active; each includes integrated clamp diode |
| VDD | Positive power supply | Single supply rail (4.5–50 V) powering both logic and output stages; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Integrated D-type latch + DMOS driver per channel | Enables synchronous, glitch-free 8-bit output control with memory retention between clock edges |
| Built-in clamp diodes (8×) | Eliminates need for external flyback diodes when driving relays, solenoids, or DC motors |
| 50 V output voltage rating | Supports direct interface with industrial 24 V and 48 V control systems without external boost or isolation |
| High noise immunity inputs | Input thresholds (0.8 V/2.0 V) and 100 kΩ internal pull-downs reduce susceptibility to EMI in noisy environments |
| Thermal derating guidance | Explicit 14.1 mW/°C derating rule enables accurate junction temperature estimation for long-term reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage latched driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TBD62783APG | 8-channel sink-type (not source-type); identical pinout but inverted output polarity and no /CLR pin | Requires load connection between VDD and Y pins instead of GND and Y pins; unsuitable where high-side switching is mandatory | Select TBD62783APG only if circuit topology permits sink-driving and asynchronous reset is unnecessary |
| ULN2803ADWR | 8-channel Darlington sink driver; 50 V rating, 500 mA per channel, no logic latch or clock input | Operates as open-collector buffer - outputs follow inputs directly; lacks synchronous update or memory function | Choose ULN2803ADWR for simple level-shifting or non-latched drive; TBD62789APG is required for clocked, memory-retentive control |
Compared with TBD62789APG, TBD62783APG offers identical packaging and voltage/current specs but reversed output configuration and missing /CLR, while ULN2803ADWR provides simpler, non-latched operation without clock or latch functionality - making TBD62789APG uniquely suited for synchronized, memory-based high-side switching.

FAQ
What is the maximum continuous output current per channel for TBD62789APG at 85°C ambient?
The TBD62789APG supports up to –400 mA per channel when only one channel is active at Ta = 25°C. At Ta = 85°C with all eight channels active and 50% duty cycle, the maximum continuous output current drops to –195 mA per channel to maintain junction temperature within safe limits. This derating is specified in the Operating Ranges table and must be applied in thermal design.
Does TBD62789APG include internal overcurrent or thermal protection?
No, the TBD62789APG does not incorporate internal overcurrent, overtemperature, or short-circuit protection circuits. As explicitly stated in the Precautions for Using section, external fusing on the VDD line and careful layout to limit fault current are mandatory. Exceeding absolute maximum ratings - even momentarily - may cause irreversible device failure.
Can TBD62789APG drive inductive loads without external components?
Yes, the TBD62789APG can drive inductive loads such as relays and solenoids without external flyback diodes, thanks to its integrated clamp diodes rated for 50 V reverse voltage and 400 mA forward current per channel. However, for high-energy inductive loads or fast-switching applications, additional snubbing may still be advisable to manage voltage overshoot.
What is the function of the /CLR pin on TBD62789APG?
The /CLR pin on TBD62789APG is an active-low asynchronous clear input that forces all eight Y outputs into high-impedance (OFF) state regardless of CLK or D-input states. This provides fail-safe shutdown capability - for example, during system fault detection or emergency stop sequences - without requiring clock synchronization.
Is TBD62789APG pin-compatible with any other Toshiba transistor arrays?
The TBD62789APG shares the same DIP20-P-300-2.54A package and pin assignment with the TBD62783APG, but they differ functionally: TBD62783APG is sink-type with no /CLR pin, while TBD62789APG is source-type with /CLR. They are not pin-compatible replacements due to opposite output polarity and missing /CLR functionality in TBD62783APG.
