DESCRIPTION

The 74AC08 is an advanced high-speed CMOS QUAD 2-INPUT AND GATE fabricated with sub-micron silicon gate and double-layer metal wiring C 2MOS tecnology. The internal circuit is composed of 2 stages including buffer output, which enables high noise immunity and stable output. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. 74AC08 QUAD 2-INPUT AND GATE PIN CONNECTION AND IEC LOGIC SYMBOLS ORDER CODES PACKAGE TUBE T & R DIP 74AC08B SOP 74AC08M 74AC08MTR TSSOP 74AC08TTR TSSOPDIP SOP

CAPACITIVE CHARACTERISTICS 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC /4 (per gate) TEST CIRCUIT C L = 50pF or equivalent (includes jig and probe capacitance) R L = R1 = 500Ω or equivalent R T = ZOUT of pulse generator (typically 50Ω ) WAVEFORM: PROPAGATION DELAYS (f=1MHz; 50% duty cycle) Symbol Parameter Test Condition Value UnitVCC (V) TA = 25°C -40 to 85°C -55 to 125°C C IN Input Capacitance 5.0 4 pF C PD Power Dissipation Capacitance (note 1) 5.0 fIN = 10MHz 33 pF
