Product details

5V bus buffer with 125°C rating

The Toshiba 74VHCT541AFT is an 8-bit non-inverting buffer with 3-state outputs from the 74VHCT logic family.

20-TSSOP footprint and supply rails

Housed in a 20-TSSOP package (4.40mm width), this buffer shares the same footprint as many other 20-pin TSSOP logic devices, simplifying PCB layout when swapping between suppliers. The supply range is 4.5V to 5.5V, so it works on a nominal 5V rail with ±10% tolerance. The 3-state outputs let you share a data bus with other drivers by asserting the output enable pin — useful in multiplexed address/data or bidirectional I/O schemes.

Frequently asked questions

Is 74VHCT541AFT a replacement for 74HCT541?

The 74VHCT541AFT is a higher-speed, lower-power variant of the 74HCT541, with the same 5V supply and 3-state output logic. It is pin-compatible and functionally identical, so it can serve as a drop-in replacement in most designs. Verify the propagation delay and drive current against your timing budget if the original 74HCT541 was marginal.

Is 74VHCT541AFT 5V tolerant?

Yes, the 74VHCT541AFT operates with a supply voltage of 4.5V to 5.5V, so it is fully 5V tolerant. Inputs and outputs are rated for 5V CMOS and TTL levels.
