3.3V voltage advanced BiCMOS technology (LVT) 16-bit transparent D-type latches with 3-state outputs Total dose hardness typical krad (Si); dependent upon orbit Single event effect: SELTH MeV/mg/cm2 Package: RAD-PAK® flat package Operating temperature range: Distributed configuration minimizes highspeed switching noise Supports mixed-mode signal operation input output voltages with 3.3V Supports unregulated battery operation down 2.7V Supports live insertion Bus-hold data inputs eliminate need external pullup resistors
DESCRIPTION:
Space Electronics' 54LVTH162373RP -PAK 16-bit transparent D-type latches with 3-state output features minimum kilorad (Si) total dose tolerance; dependent upon orbit. 54LVTH162373RP designed voltage (3.3V) operation, with capability provide interface system environment. suitable implementing buffer registers, ports, bidirectional drivers, working registers. 54LVTH162373RP used 8-bit latches 16-bit latch. When latch-enable (LE) input low, output latched levels data inputs. When high, outputs follow inputs. buffered output-enable input used place eight outputs either normal logic state high impedance state. high impedance state, outputs neither load drive lines significantly. high impedance state increased drive provide capability drive lines without need interface pullup components. does affect internal operations latch. data retained data entered while outputs high impedance state. 54LVTH162373RP available with packaging screening Class
