Overview: ® 74VHC373 OCTAL D-TYPE LATCH WITH 3 STATE OUTPUT NON INVERTING s s s s s s s s s s HIGH SPEED: tPD = 5.0 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 4 µA (MAX.) at TA = 25 oC HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.) POWER DOWN PROTECTION ON INPUTS SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 5.5V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 373 IMPROVED LATCH-UP IMMUNITY LOW NOISE: VOLP = 0.9V (Max.) M (Micro Package) T (TSSOP Package) ORDER CODES : 74VHC373M 74VHC373T While the LE input is held at a high level, the Q outputs will follow the data inputs precisely. When the LE is taken low, the Q outputs will be latched precisely at the logic level of D input data. While the (OE) input is low, the 8 outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

The 74VHC373 is an advanced high-speed CMOS OCTAL D-TYPE LATCH with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
This 8 bit D-Type latch is controlled by a latch enable input (LE) and an output enable input (OE).
