Decoder/Demultiplexer Single 3-to-8 16-Pin SOP T/R

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.The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels.All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

• 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 OUTPUT 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
