3至8线译码器反相 3 TO 8 LINE DECODER INVERTING

DESCRIPTION

The 74AC138 is an advanced high-speed CMOS 3 TO 8 LINE DECODER INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.

■ HIGH SPEED: tPD = 4.5ns TYP. at VCC = 5V

■ LOW POWER DISSIPATION:

   ICC = 4µAMAX. at TA=25°C

■ HIGH NOISE IMMUNITY:

   VNIH = VNIL = 28 % VCC MIN.

■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

   |IOH| = IOL = 24mA MIN

■ BALANCED PROPAGATION DELAYS:

   tPLH = tPHL

■ OPERATING VOLTAGE RANGE:

   VCC OPR = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 138

■ IMPROVED LATCH-UP IMMUNITY
