DESCRIPTION
The 74ACT138 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.
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 function is inhibited and all the 8 outputs go to high.
Three enable inputs are provided to ease cascade connection and application of address decoders for memory systems.
■ HIGH SPEED: tPD = 5ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
ICC = 4μA(MAX.) at TA=25°C
■ COMPATIBLE WITH TTL OUTPUTS
VIH = 2V (MIN.), VIL = 0.8V (MAX.)
■ 50? TRANSMISSION LINE DRIVING CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 24mA (MIN)
■ BALANCED PROPAGATION DELAYS:
tPLH = tPHL
■ OPERATING VOLTAGE RANGE:
VCC (OPR) = 4.5V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 138
■ IMPROVED LATCH-UP IMMUNITY
