5 ns (TYP.
) at VCC = 5V LOW POWER DISSIPATION: ICC = 8 µA (MAX.
) at TA = 25 oC HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.
) 50Ω TRANSMISSION LINE DRIVING CAPABILITY SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24 mA (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
B M (Plastic Package) (Micro Package) ORDER CODES : 74AC138B go low.
If enable input G1 is held low or either G2A or G2B is held high, the decoding function is inhibited and all the 8 outputs go to high.
Tree enable inputs are ...
