SL74HC323 Datasheet | System Logic Semiconductor

features a multiplexed parallel input/output data port to active full 8-bit handling in a 20 pin package. Due to the large output drive capability and the 3-state feature , this device is ideally suited for interface with bus lines in a bus-oriented system. ORDERING INFORMATION Two Mode-Select inputs and two Output Enable inputs are used to SL74HC323N Plastic choose the mode of operation as listed in the Function Table. SL74HC323D SOIC Synchronous parallel loading is acplished by taking both Mode TA = -55° to 125° C for all packages Select lines, S 1 and S 2, high. This places the outputs in the highimpedance state, which permits data applied to the data port to be clocked into the register. Reading out of the register can be acplished when the outputs are enabled. The active-low synchronous Reset overrides all other inputs. - Outputs Directly Interface to CMOS, NMOS, and TTL PIN ASSIGNMENT - Operating Voltage Range: 2.0 to 6.0 V - Low Input Current: 1.0 µA - High Noise Immunity Characteristic of CMOS Devices LOGIC DIAGRAM PIN 20=VCC PIN 10 = GND System Logic Semiconductor MAXIMUM RATINGS - Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL - Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±35 ±75 750 500 -65 to +150 260 Unit V V V m A m A m A m W °C °C Maximum Ratings are those values beyond which damage to the device may occur.
