74HC540
TC74HC540,541AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC540AP,TC74HC540AF,TC74HC541AP,TC74HC541AF Octal Bus Buffer TC74HC540AP/AF TC74HC541AP/AF Inverting, 3-State Outputs Non-Inverting, 3-State Outputs The TC74HC540A/TC74HC541A are high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC540A is an inverting type, and the TC74HC541A is a non-inverting type. When either G1 or G2 are high, the terminal outputs are in the high-impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage. TC74HC540AP, TC74HC541AP TC74HC540AF, TC74HC541AF Features • High speed: tpd = 10 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output Drive Capability: 15 LSTTL loads • • Symmetrical output impedance: |IOH| = IOL = 6 mA (min) ∼ Balanced propagation delays: tpLH − tpHL • Wide operating voltage range: VCC (opr) = 2 to 6 V • Pin and function compatible with 74LS540/541 1 Weight DIP20-P-300-2.54A SOP20-P-300-1.27A : 1.30 g (typ.) : 0.22 g (typ.) 2007-10-01
