Peripheral circuit EB1562544877 astable monostable RC timer 500 kHz DIP-8

EB1562544877 is a peripheral RC timer circuit in a compact DIP-8 through-hole package. The device supports both astable and monostable modes, enabling pulse generation, timing intervals and basic waveform shaping. With a specified maximum operating frequency of 500 kHz, this timer is suitable for low- to medium-speed timing tasks in prototypes, control circuits and simple oscillator designs. The DIP-8 form factor allows easy placement on breadboards and through-hole PCBs for quick testing and integration.

Advantages

The timer combines dual-mode operation—astable for free-running oscillation and monostable for single-shot timing—in a single DIP-8 package, reducing component count and simplifying circuit layout. Its 500 kHz maximum frequency rating provides adequate bandwidth for many signal generation and gating needs without requiring surface-mount assembly. The through-hole format ensures straightforward soldering and replacement during development. Standard RC external components determine timing characteristics, offering flexible adjustment of pulse width and frequency.

Suitable for

• Prototyping on breadboards and through-hole PCBs
• Low- to medium-frequency pulse generation and timing
• Oscillator and clock-source circuits for simple projects
• Debouncing, gating and basic waveform shaping tasks

Key specifications

• Package type: DIP-8 through-hole
• Operating modes: astable (free-running) and monostable (one-shot)
• Maximum frequency: 500 kHz
• Timing method: external resistor-capacitor (RC) network
• Typical applications: timing, pulse generation, waveform shaping

How to use

Install the component into a DIP-8 socket or solder it to a through-hole PCB, ensuring correct pin orientation. Configure the circuit for astable operation by connecting the appropriate resistors and capacitor to the timing pins to set oscillation frequency and duty cycle, or configure for monostable operation by wiring the trigger and timing components to produce a single output pulse of defined width. Use recommended resistor and capacitor values within the device's electrical limits to achieve target timing intervals. Verify operation at the intended supply voltage and test across the anticipated temperature range if needed for reliable performance.

Usage recommendations

Use low-leakage capacitors and stable precision resistors for accurate timing at longer intervals; keep wiring and PCB traces between timing pins short to minimize stray capacitance and noise. For frequencies approaching the 500 kHz rating, verify signal integrity and consider layout and decoupling to reduce jitter. When replacing or prototyping, use sockets to facilitate component swaps and to protect the board from heat during soldering.
