TECHNICAL DATA KK74ACT299 8-Bit Bidirectional Universal Shift Register with Parallel I/O High-Speed Silicon-Gate CMOS The KK74ACT299 is identical in pinout to the LS/ALS299, HC/HCT299. The KK74ACT299 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74ACT299 features a multiplexed parallel input/output data port to achieve 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. Two Mode-Select inputs and two Output Enable inputs are used to choose the mode of operation as listed in the Function Table. Synchronous parallel loading is accomplished by taking both ModeSelect lines, S1 and S2, 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 accomplished when the outputs are enabled. The active-low asynchronous Reset overrides all other inputs. • TTL/NMOS Compatible Input Levels • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 4.5 to 5.5 V • Low Input Current: 1.0 µA; 0.1 µA @ 25°C • Outputs Source/Sink 24 mA ORDERING INFORMATION KK74ACT299N Plastic KK74ACT299DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM PIN 20=VCC PIN 10 = GND 1 KK74ACT299 MAXIMUM RATINGS* Symbol Parameter Value Unit -0.5 to +7.0 V VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Input Current, per Pin ±20 mA IOUT DC Output Sink/Source Current, per Pin ±50 mA ICC DC Supply Current, VCC and GND Pins ±50 mA PD Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ 750 500 mW -65 to +150 °C 260 °C VOUT IIN Tstg TL Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) * Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. 2 KK74ACT299 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol Parameter Test Conditions Guaranteed Limits V 25 °C -40°C to 85°C Unit VIH Minimum HighLevel Input Voltage VOUT= 0.1 V or VCC-0.1 V 4.5 5.5 2.0 2.0 2.0 2.0 V VIL Maximum Low Level Input Voltage VOUT= 0.1 V or VCC-0.1 V 4.5 5.5 0.8 0.8 0.8 0.8 V VOH Minimum HighLevel Output Voltage IOUT ≤ -50 µA 4.5 5.5 4.4 5.4 4.4 5.4 V 4.5 5.5 3.86 4.86 3.76 4.76 4.5 5.5 0.1 0.1 0.1 0.1 VIN= VIH or VIL IOL=24 mA IOL=24 mA 4.5 5.5 0.36 0.36 0.44 0.44 ±0.1 ±1.0 µA 1.5 mA ±6.0 µA * VIN=VIH or VIL IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA V * IIN Maximum Input Leakage Current VIN=VCC or GND 5.5 ∆ICCT Additional Max.
