L3845B1 - Brand New STMicroelectronics IC Chips
-
Description
The L3845B1 is an electronic component model in the product category of IC Chips. It provides DC loop termination for analog trunk lines. The V-I characteristics of the circuit is equivalent to a fixed voltage drop (zener-like characteristic) in series with an external resistance that determines the slope of the DC characteristic. Additionally, an external low voltage electrolytic capacitor causes the circuit to exhibit a very high impedance to all AC signals above a minimum frequency, determined by the capacitor itself and a 20 K nominal resistor integrated on the chip.
Specifications and features
The L3845B1 has the following specifications and features:
- On-chip polarity guard
- Meets DC line characteristics of either CCITT and EIA RS 464 specs
- Pulse function
- High AC impedance
- Off-hook status detection output
- Low external component count
Application Scenarios
The L3845B1 is commonly used in analog trunk lines for providing DC loop termination. It is suitable for applications requiring high AC impedance and off-hook status detection.
