Product details

What the 1ns propagation delay means for the bus

The 1ns propagation delay adds minimal hold time to the bus. Compared to the 74FCT573 with 8.5ns delay, this latch leaves more margin in a 10 ns cycle.

Supply voltage and drive: 1.8V logic compatibility

The 1.65V minimum supply allows operation on a 1.8V rail without a level shifter. The 24mA output drive handles multiple loads on a short backplane trace.

It is ROHS3 compliant, which clears it for EU and California markets without exemption paperwork. For a production BOM, this is a stable line item with no imminent last-time-buy risk.

Frequently asked questions

Is SN74ALVCH16841DGGR compatible with 1.8V logic?

Yes. The supply voltage range is 1.65V to 3.6V, so it runs directly on a 1.8V rail. All inputs and outputs are 1.8V-compatible without external level translation.

What is an equivalent part to SN74ALVCH16841DGGR from other manufacturers?

The 74FCT573APC from IDT (now Renesas) is a functional alternative — it is also a D-type transparent latch with tri-state outputs, but it is an 8-bit device in a through-hole package, runs on 4.75V supply, has 8.5ns propagation delay, and operates from 0°C to 70°C. The SN74ALVCH16841DGGR is a 20-bit surface-mount part with much faster speed, wider supply range, and industrial temperature rating — they are not pin-compatible but serve similar bus-latching roles.
