The 74VHC573 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).
While the LE input is held at a high level, the Q PIN CONNECTION AND IEC LOGIC SYMBOLS June 1999 1/10 74VHC573 INPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1 2, 3, 4, 5, 6, 7, 8, 9 12, 13, 14, 15, 16, 17, 18, 19 11 10 20 SYMBOL OE D0 to D7 NAME AND FUNCT ION 3 State Output Enable Input (Active LOW) Data Inputs Q0 to Q7 3 State Latch Outputs LE GND VCC Latch Enable Input Ground (0V) Positive Supply Voltage TRUTH TABLE INPUTS OE H L L L LE X L H H D X X L H O
® 74VHC573 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 573 IMPROVED LATCH-UP IMMUNITY LOW NOISE: VOLP = 0.9V (Max.) M (Micro Package) T (TSSOP Package) ORDER CODES : 74VHC573M 74VHC573T 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.
