description

The SN74BCT2414 is a decoder specially designed to be used in memory systems with battery backup during

power failure. The two independent 2-line to 4-line decoders with separate and common control inputs may be

externally cascaded to implement a 3-line to 8-line decoder.

The circuit has two supply voltage inputs: the voltage monitor (bandgap) is powered via the VCC terminal; the

internal logic of the circuit is powered via the Vbat terminal. In case VCC drops below 3.65 V (nominal), the voltage

monitor forces the voltage-control (VS) and decoder outputs (Y) to the high level. VS may be used to disconnect

the supply voltage of the memories (Vbat) from the system supply. This output is switched off when the on-chip

supply voltage monitor detects a power failure.

The SN74BCT2414 is characterized for operation from 0

°C to 70°C.
