TC74VHCT540AFK Overview
TC74VHCT540,541AF/AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT540AF, TC74VHCT540AFK TC74VHCT541AF, TC74VHCT541AFK Octal Bus Buffer TC74VHCT540AF/AFK Inverted, 3-State Outputs The TC74VHCT540A is an inverting type and, the TC74VHCT541A is a non-inverting type. When either G1 or G2 are high, the terminal outputs are in the highimpedance state. The input voltage are patible with TTL output voltage. These devices may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. Note: Output in off-state TC74VHCT540AFK, TC74VHCT541AFK
