TC74LVX373

The TC74LVX373 is a high speed CMOS OCTAL LATCH with 3-STATE OUTPUT fabricated with silicon gate CZMOS technology.Designed for use in 3.3 Volt systems, it achieves high speed operation while maintaining the CMOS low power dissipation.This device is suitable for low voltage and battery operated systems.This 8bit D-type latch is controlled by a latch enable input (LE) and a output enable input (OE).When the OE input is high, the eight outputs are in a high impedance state.

Features of the TC74LVX373 are:(1)high speed: tpd=5.8ns (Typ) at VCC=3.3V;(2)low power dissipation: ICC = 4A (Max) at TA = 25;(3)power down protection provided on inputs;(4)balanced propagation delays:tpLHtpHL;(5)low noise: VOLP =0.8V(max);(6)pin and function compatible with 74HC373;(7)input voltage level:VIL=0.8V(Max)(Vcc=3V),VIH=2.0V(Max)(Vcc=3V).An input protection circuit ensures that 0 to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up.This circuit prevents device destruction due to mismatched supply and input voltages.

The absolute maximum ratings of the TC74LVX373 can be summarized as:(1)supply voltage range:-0.5 to 7.0 V;(2)storage temperature:-65 to +150;(3)DC input voltage:-0.5 to 7.0 V;(4)input diode current:-20mA;(5)power dissipation:180mW.The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances,etc.).These TOSHIBA products are neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or bodily injury ("Unintended Usage").
