Product details

Single-bit D-type with set and reset — 200 MHz in a 1.4x1 mm package

It includes both Set (Preset) and Reset inputs, and provides complementary Q and Q̅ outputs. Clock frequency reaches 200 MHz, and the output can source or sink 32 mA symmetrically. Propagation delay is 4.4 ns at 5 V with a 50 pF load. The device is housed in an 8-X2SON package measuring 1.4 x 1.0 mm, suited for dense PCB layouts in portable and industrial equipment.

Supply voltage flexibility and temperature range

Quiescent current is 10 µA typical, which is negligible in most applications but worth noting for battery-powered designs that spend long periods in idle.

Output drive and timing margin

Symmetric 32 mA output drive at both high and low levels means the part can drive a 50 pF load with a 4.4 ns propagation delay at 5 V. This drive strength is sufficient for clock distribution to multiple loads or for driving short PCB traces without a buffer. At lower supply voltages (e.g., 1.8 V), the propagation delay will increase — the 4.4 ns figure is at 5 V, so budget additional margin when operating at 3.3 V or 1.8 V. Input capacitance is 5 pF, which is low enough to not load the driving gate significantly at 200 MHz.

The 8-X2SON package (1.4 x 1.0 mm body, 0.5 mm pitch) is a leadless package with exposed pads underneath. It requires a solder-paste stencil designed for the specific land pattern — the datasheet's recommended footprint should be followed exactly. Reflow profile must match the solder paste specification; the small thermal mass means the package reaches peak temperature quickly.

Frequently asked questions

Can the SN74LVC1G74DQER be used at 3.3 V?

Yes, the supply range is 1.65 V to 5.5 V, so 3.3 V is well within the operating window. At 3.3 V the propagation delay will be slightly higher than the 4.4 ns figure specified at 5 V, but the part is fully characterized across the entire supply range.

What is the difference between SN74LVC1G74 and SN74LVC1G74DQER?

The SN74LVC1G74 is the base product number for the entire family of single D-type flip-flops. The SN74LVC1G74DQER is a specific ordering code that denotes the 8-X2SON package (DQE) and the tape-and-reel packaging (R). The electrical specifications are identical across all package variants of the SN74LVC1G74.
