Product details

Active production — what that means for your BOM

The SN74LVC112AD: ROHS3 compliant per the evidence, with no exemption flags — clears EU and similar regulatory requirements without a waiver.

JK flip-flop timing and trigger

Rated clock frequency of 150 MHz sets the counter/divider ceiling — the 5.9 ns max propagation delay at 3.3 V and 50 pF load defines the timing budget for the downstream logic; at lower supply voltages the delay increases.

Power and drive

Quiescent current is 10 µA typical — low enough for battery-backed or always-on logic sections where every microamp counts. Output drive capability is 24 mA source and sink at rated VCC — sufficient to fan out to multiple CMOS inputs or drive a low-current LED directly.

Frequently asked questions

Will SN74LVC112AD drop into a board designed for SN74HCS74QBQARQ1?

No — the SN74HCS74QBQARQ1 is a positive-edge triggered D-type flip-flop with automotive AEC-Q100 qualification, while the SN74LVC112AD is a negative-edge triggered JK-type. The trigger edge and logic function differ, so a board spin or logic redesign is required.

What is the maximum clock frequency and propagation delay?

The SN74LVC112AD is rated for 150 MHz clock frequency. Maximum propagation delay is 5.9 ns at 3.3 V supply with a 50 pF load — this sets the timing margin for downstream logic.
