8N3DV85KC-0050CDI8 is a programmable timer and oscillator. This device is a versatile timing circuit which combines a monolithic CMOS timer and oscillator with voltage-controlled time base. It provides the following features: adjustable time delay accurately controlled by an externally applied voltage, and wide timing range from 0.4s to 10s. The 8N3DV85KC-0050CDI8 can be a relatively simple solution for timing and oscillator applications such as delaying/stabilizing circuits, waveform generators, and control/monitoring in a very broad range of applications, including automotive, industry, and entertainment.

The 8N3DV85KC-0050CDI8 has two different delay modes: normal delay mode and independent delay mode. In the normal delay mode, it can be used for timing, duration, and waveform generation. Normal delay mode requires a pulse or a digital logic input to start and reset the timing cycle. For example, a pulse input starts the timing cycle, and when the delay times out, the output swings low, to indicate the end of the timing cycle. The independent delay mode is useful as a one-shot or a timer with an automatic reset. In this mode, the timing cycle is initiated and reset by the rising or falling edge of the digital logic input. This makes the device suitable for applications where an output pulse is needed with variable duration.

Moreover, 8N3DV85KC-0050CDI8 includes an adjustable bias generator which can be used as a reference voltage for a voltage-controlled time base. This generator supplies a voltage proportional to the clock frequency, which can be used to control the timing characteristics of connected circuits. The design of the bias generator is advantageous in that it does not require an external bias resistor and it allows for fast transition times for output swing changes. The device also includes circuitry for power-on reset of the circuit.

The 8N3DV85KC-0050CDI8 has certain general applications. Examples of such applications include, but are not limited to, adjustable time delay circuits (e.g. clock delays and timers), waveform generators, control/monitoring circuits (e.g. PLCs and temperature control systems), and using the PWM output to control a voltage-controlled device. Each of these applications satisfies the programmable timer and oscillator requirement of applying a time base variable voltage to establish the timing cycle.

The 8N3DV85KC-0050CDI8 is suitable for a wide variety of applications. In particular, it is well suited for automotive, industry, and entertainment applications where the digital input can be used to initiate and reset timing cycles. The device is also favored for its small size, low cost, and its wide application range. The 8N3DV85KC-0050CDI8’s adjustable time delay and wide timing range provide an excellent solution for applications in many different fields.
