Specifications

The TC74HCT541AF(EL) operates from a supply voltage of 4.5V to 5.5V. It has a propagation delay typically in the range of 10-15ns. The output drive capability is sufficient to drive multiple TTL loads. The three-state outputs allow the device to be effectively disconnected from the bus, allowing other devices to drive the bus without contention. The input logic levels are compatible with standard TTL voltage levels. It typically comes in a SOIC package.
