NTE74HCT08

NTE74HCT08 Integrated Circuit TTL − High Speed CMOS, Quad, 2−Input AND Gate Description: The NTE74HCT08 is a logic function in a 14−Lead plastic DIP type package fabricated using advanced silicon−gate CMOS technology which provides the inherent benefits of CMOS − low quiescent power and wide power supply range. This device is input and output characteristic and pinout compatible with standard NTE74LS logic families. All inputs are protected from static discharge damage by internal diodes to VCC and ground. The NTE74HCT08 is intended to interface between TTL and NMOS components and standard CMOS devices. This device is also a plug−in replacement for LS−TTL devices and can be used to reduce power consumption in existing designs.

Stresses exceeding the Absolute Maximum Ratings may damage the device. The device may not function or be operable above the Recommended Operating Conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the Recommended Operating Conditions may effect device reliability. The Absolute Maximum Ratings are stress ratings only. Note 2. Unless otherwise specified, all voltages are referenced to GND. Note 3. Power Dissipation temperature derating: 12mW/°C from +65°C to +85°C. Recommended Operating Conditions: Parameter Symbol Min Typ Max Unit VCC 4.5 − 5.5 V VIN, VOUT 0 − VCC V Operating Temperature Range TA −40 − +85 °C Input Rise or Fall Times tr, tf − − 500 ns Supply Voltage DC Input or Output Voltage DC Electrical Characteristics: (VCC = 5V ±10% unless otherwise specified) TA = +25°C Typ Guaranteed Limits Parameter Symbol Minimum High Level Input Voltage VIH − 2.0 2.0 V Maximum Low Level Input Voltage VIL − 0.8 0.8 V Minimum High Level Output Voltage VOH VCC −0.1 V Minimum Low Level Output Voltage VOL Test Conditions TA = −40° to +85°C VIN = VIH or VIL VIN = VIH Unit |IOUT| = 20μA VCC VCC −0.1 |IOUT| = 4.0mA, VCC = 4.5V 4.2 3.98 3.84 V |IOUT| = 4.8mA, VCC = 5.5V 5.2 4.98 4.84 V 0 0.1 0.1 V |IOUT| = 4.0mA, VCC = 4.5V 0.2 0.26 0.33 V |IOUT| = 4.8mA, VCC = 5.5V 0.2 0.26 0.33 V |IOUT| = 20μA Maximum Input Current IIN VIN = VCC or GND, VIH or VIL − ±0.1 ±1.0 μA Maximum Quiescent Supply Current ICC VIN = VCC or GND, IOUT = 0μA − 2.0 20 μA VIN = 2.4V or 0.5V, Note 4 − 1.2 1.4 mA Note 4.
