General Description

Name OSH, LH LO BO VDD VSS T1, T2, TC TO Function Melody mode control inputs.

Built-in pull-down resistors mean LOW-level signals are obtained when inputs are open circuit.

The resistance of the pull-down resistor varies with the applied voltage, as described in the Electrical Characteristics.

Overview

www.DataSheet4U.com CF1156 series Melody LSIs OVERVIEW The CF1156 series are CMOS melody LSIs with built-in LED driver that, together with a battery and piezoelectric buzzer, operate in one of 3 melody modes determined by input level or bonding options.

They also feature an oscillator stop function in non-play mode and a variable pull-down resistance function that responds to input levels in order to reduce power consumption, reduce cost, and extend battery life, making them ideal in a wide range of applications including greeting cards and toys.
