74AC138MTR Datasheet PDF - ST Microelectronics

●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 = 4µA(MAX.) 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
