What is IC MT8870 Price

What is IC MT8870 Price

The MT8870 is an integrated circuit designed for DTMF tone decoding. It can detect and decode all 16 DTMF tone pairs into a 4-bit code. The MT8870 is commonly used in telephone dialing circuits for decoding the numbers pressed on a telephone keypad.

MT8870 Pricing Factors

There are several factors that affect the pricing of the MT8870 IC:

Manufacturing Cost

Like most integrated circuits, the manufacturing cost of the MT8870 depends on the complexity of the chip design and fabrication process. More complex ICs with smaller transistor geometries generally cost more to produce.


ICs are sold in different package types like DIP, SOIC, QFP, etc. The package type affects the price with smaller packages generally being more expensive. The MT8870 is commonly available in 16-pin DIP and SOIC packages.

Order Quantity

IC pricing is largely dependent on order volume. Buying ICs in bulk lowers the per unit cost. The MT8870 can range from around $1.5-$2 in single quantities to under $1 in large volumes.


There are different brands offering the MT8870 IC. While electrically equivalent, pricing can vary slightly between brands. Well-known suppliers include NXP, ON Semiconductor, Adafruit.

Current MT8870 Pricing

Here are some typical price ranges for the MT8870 based on order quantity:

1-9 units$1.5 – $2 per unit
10-99 units$1 – $1.5 per unit
100-999 units$0.75 – $1 per unit
1000+ unitsUnder $0.75 per unit

Prices will also depend on the distributor and packaging. When comparing prices, be sure to compare the same package type and order quantity range.

Uses for MT8870 ICs

Here are some common applications for the MT8870:

  • DTMF decoder in telephone dialing circuits
  • DTMF tone decoder in cell phones
  • DTMF tone detection for microcontrollers
  • DTMF tone extraction in voice mail systems
  • Decoding signals for remote controls
  • Frequency detection in electronic musical instruments

The MT8870 provides an affordable and reliable way to decode DTMF tones in a range of electronic devices. Its low cost makes it suitable for high volume commercial products.

Frequently Asked Questions

What is the difference between MT8870 and MT8870D?

The MT8870D is functionally equivalent to the MT8870 except it has much lower power consumption, around 1mA vs 2mA for the standard MT8870. The D version is more suitable for battery powered applications.

Are there alternatives to the MT8870 IC?

Some alternatives include the HT9170B DTMF receiver and M-8870 DTMF decoder ICs which provide similar DTMF tone decoding functionality. The Holtek HT9170B is comparable in pricing to the MT8870.

What package options are available for MT8870?

Common packaging options include 16-pin DIP, 16-pin SOIC, 18-pin SOIC, and custom SMT packages. DIP and SOIC through-hole packages are widely available while SMT provides a compact surface mount option.

Is the MT8870 only used for DTMF decoding?

The primary function of the MT8870 is DTMF tone decoding. However, it can also be used as a general dual-tone decoder for detecting other frequencies outside the DTMF spectrum.

What is the typical supply voltage range for MT8870?

The supply voltage range is 3V to 5.5V. It can operate down to 2.4V at slower speeds. 5V is the most common supply voltage used.
