Overview
M74HC138 3 TO 8 LINE DECODER (INVERTING) s HIGH SPEED: tPD = 13ns (TYP.
) at VCC = 6V s LOW POWER DISSIPATION: ICC = 4µA(MAX.
) at TA=25°C s HIGH NOISE IMMUNITY: VNIH = VNIL = 28 % VCC (MIN.
) s SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) s BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL s WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 138 DESCRIPTION The M74HC138 is an high speed CMOS 3 TO 8 LINE DECODER fabricated with silicon gate C2MOS technology.
If the device is enabled, 3 binary select inputs (A, B, and C) determine which one of the outputs will go low.
If enable input G1 is held low or either G2A or G2B is held high, the decoding fun...
