The 74HC; 74HCT has octal non-inverting buffer/line drivers with 3-state Ci input capacitance. -. -. pF. CPD power dissipation. The SNx4HC octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock. I need a logic buffer for 8-bit microcontroller port, like 74HC, but with an output current of more than 20mA, to drive high current LED.

Two useful variations of these American symbols are also widely used and are shown added to a standard inverter symbol in Figure 2 ; the left-hand symbol is internationally recognized and indicates that the logic element has a Schmitt trigger input action; the right-hand symbol — which is widely used but is not universally recognized — indicates that the logic element has an open-drain o.
How do you get an MCU design to market quickly? The circuit action is such that the output is pulled low when any input is low, and only goes high when all three inputs are high, thus giving an AND action. Basic sets of two-input positive and negative logic equivalents. Contact For Free Shipping. Our company aim at meeting your need, supply you high quality and inexpensive goods. Only buyers who purchased the product may leave a review. Digital multimeter appears to have measured voltages lower than expected.
Very satisfied with the services: Synthesized tuning, Part 2: Could you provide technology support9 A: I need a logic buffer for 8-bit microcontroller port, like 74HC, but with an output current of more than 20mA, to drive high current LED.
