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
