1 / 7 page TC74HCT540,541AP/AF 2007-10-01 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT540AP,TC74HCT540AF TC74HCT541AP,TC74HCT541AF Octal Bus Buffer with TTL Input Level TC74HCT540AP/AF Inverting, 3-State Outputs TC74HCT541AP/AF Non-Inverting, 3-State Outputs The TC74HCT540A/TC74HCT541A are high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. These devices may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. They achive the high speed operation similar to equivalent LSTTL while maintaing the CMOS low power dissipation. The TC74HCT540A is an inverting type, and the TC74HCT541A is a non-inverting type. When either 1 G or 2 G 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. Features • High speed: tpd = 10 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • Compatible with TTL outputs: VIL = 0.8 V (max) VIH = 2.0 V (min) • Wide interfacing ability: LSTTL, NMOS, CMOS • Output drive capability: 15 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 6 mA (min) • Balanced propagation delays: tpLH ∼− tpHL • Pin and function compatible with 74LS540/541 TC74HCT540AP, TC74HCT541AP TC74HCT540AF, TC74HCT541AF Weight DIP20-P-300-2.54A : 1.30 g (typ.) SOP20-P-300-1.27A : 0.22 g (typ.) |
