description

The SN74BCT2414 is a decoder specially designed to be used inmemory systems with battery backup during power failure. The twoindependent 2-line to 4-line decoders with separate and commoncontrol inputs may be externally cascaded to implement a 3-line to8-line decoder.

The circuit has two supply voltage inputs: the voltage monitor(bandgap) is powered via the V_CC terminal; the internallogic of the circuit is powered via the V_bat terminal. Incase V_CC drops below 3.65 V (nominal), the voltage monitorforces the voltage-control (VS) and decoder outputs (Y) to the highlevel. VS may be used to disconnect the supply voltage of thememories (V_bat) from the system supply. This output isswitched off when the on-chip supply voltage monitor detects a powerfailure.

The SN74BCT2414 is characterized for operation from 0°C to70°C.
