Dual 2-to-4 Line Decoder 3-to-8 Line Decoder
The TC74HC155A is a high speed CMOS DUAL 2-to-4 LINE DECODER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
Features
• High speed: tpd= 12 ns typ. at VCC= 5 V
• Low power dissipation: ICC= 4 μA max at Ta = 25°C
• High noise immunity: VNIH= VNIL= 28% VCCmin
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL= 4 mA min
• Balanced propagation delays: tpLH∼ − tpHL
• Wide operating voltage range: VCCopr = 2 to 6 V
• Pin and function compatible with 74LS155
