descriptionThe 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.
