产品概述
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.
