Part Details:

74VHC373 OCTAL D-TYPE LATCH WITH 3 STATE OUTPUTS NON INVERTING s HIGH SPEED: t PD = 5.0 ns (TYP.) at VCC = 5V s LOW POWER DISSIPATION:ICC = 4 µA (MAX.) at TA=25°C s HIGH NOISE IMMUNITY:VNIH = VNIL = 28% VCC (MIN.) s POWER DOWN PROTECTION ON INPUTS s SYMMETRICAL OUTPUT IMPEDANCE: SOP TSSOP |IOH| = IOL = 8 mA (MIN) s BALANCED PROPAGATION DELAYS: Table 1: Order Codes tPLH tPHL s OPERATING VOLTAGE RANGE: PACKAGE T & R VCC(OPR) = 2V to 5.5V SOP 74VHC373MTR s PIN AND FUNCTION COMPATIBLE WITH TSSOP 74VHC373TTR 74 SERIES 373 s IMPROVED LATCH-UP IMMUNITY s LOW NOISE: VOLP = 0.9V (MAX.) precisely at the logic level of D input data. Whilethe (OE) input is low, the 8 outputs will be in a DESCRIPTION normal logic state (high or low logic level) and The 74VHC373 is an advanced high-speed while (OE) is in high level, the outputs will be in a CMOS OCTAL D-TYPE LATCH with 3 STATE high impedance state. OUTPUTS NON INVERTING fabricated with Power down protection is provided on all inputs sub-micron silicon gate and double-layer metal and 0 to 7V can be accepted on inputs with no wiring C2MOS technology. regard to the supply voltage. This device can be These 8 bit D-Type latch are controlled by a latch used to interface 5V to 3V. enable input (LE) and an output enable input (OE). All inputs and outputs are equipped with
