Product details

Quad XOR gate for wide-supply logic

It operates over a 3V to 18V supply range, drawing a maximum quiescent current of just 1 µA, and is specified across the full -55°C to 125°C military temperature range. Packaged in a 14-SOIC surface-mount package, it provides four independent XOR gates, each with two inputs, making it suitable for parity checking, comparator circuits, and controlled inversion in industrial control, automotive, and aerospace systems where a wide supply tolerance and low static power are required.

Supply flexibility and speed trade-off

The 3V to 18V supply range allows the CD4070BM to interface directly with 5V, 12V, and 15V logic families without level shifters, a key advantage over lower-voltage XOR gates such as the SN74LVC86APWR (1.65V to 3.6V). The trade-off is propagation delay: at 15V and 50 pF load, the CD4070BM is rated at 100 ns maximum, versus 4.4 ns at 3.3V for the SN74LVC86APWR. For slow control signals, panel switches, or sensor debounce, the 100 ns delay is acceptable; for high-speed data buses, the 74LVC part is the better fit.

Temperature range and quiescent current

Output current is 3.4 mA for both high and low states.

Frequently asked questions

What is the difference between CD4070BM and CD4070BE?

The CD4070BM is the surface-mount 14-SOIC package variant; the CD4070BE is the through-hole 14-DIP package. Both use the same 4000B-series XOR gate die with identical electrical specifications.

Can CD4070BM be used as a replacement for CD4070B?

Yes, the CD4070BM is the surface-mount SOIC version of the CD4070B family. The 'B' suffix indicates the 4000B-series buffered output stage. If your original BOM specified the CD4070B in a DIP package, verify the footprint matches the 14-SOIC of the BM variant.
