It is ideal for 1.65 to 3.6 VCC operations and low power and low noise applications. These 8 bit D-Type latch are controlled by a latch enable input (LE) and an output enable input (OE). While the LE inputs is held at a high level, the Q PIN CONNECTION AND IEC LOGIC SYMBOLS February 2002 SOP TSSOP ORDER CODES PACKAGE TUBE T&R SOP TSSOP 74LVC573AM 74LVC573AMTR 74LVC573ATTR outputs will follow the data input precisely or inversely. When the LE is taken low, the Q outputs will be latched precisely or inversely 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. This device is designed to interface directly High Speed CMOS systems with TTL and NMOS components. It has more speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. 1/10 74LVC573A INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION TRUTH TABLE PIN No SYMBOL NAME AND FUNCTION 1 OE 2, 3, 4, 5, 6, 7, 8, 9 12, 13, 14, 15, 16, 17, 18, 19 11 10 20 D0 to D7 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 INPUTS OUTPUT OE LE D Q H X X L L X L L H H L H Z NO CHANGE L H X : Don’t Care Z : High Impedance ABSOLUTE MAXIMUM RATINGS Symbol V CC Parameter Supply Voltage Value Unit -0.5 to +7.0 V VI DC Input Voltage -0.5 to +7.0 V VO DC Output Voltage (V CC = 0V) -0.5 to +7.0 V VO DC Output Voltage (High or Low State) (note 1) IIK DC Input Diode Current IOK IO -0.5 to VCC + 0.5 V - 50 mA DC Output Diode Current (note 2) - 50 mA DC Output Current ± 50 mA ± 100 mA -65 to +150 °C 300 °C ICC or IGND DC VCC or Ground Current per Supply Pin Tstg Storage Temperature TL Lead Temperature (10 sec) Absolute Maximum Ratings are those values beyond which damage to the device may occur.
