Description
With 3-state outputs, the SN74HC374NSR can effectively drive bus lines or buffer memory address registers. When the output enable input is high, the outputs are in a high-impedance state; when low, the outputs reflect the current state of the flip-flops.
Operating from a voltage range of 2V to 6V, it is suitable for use in both TTL and CMOS logic levels. The device has a typical propagation delay of 13ns at 5V and features low power consumption. Its non-inverting outputs and capability to drive 15 LSTTL loads make it ideal for high-speed memory interfacing and data bus applications. The SN74HC374NSR is available in an SOIC package for surface mounting.

Pinout
The primary function of the SN74HC374NSR is to store and transfer data. It has eight D-type flip-flops with buffered common clock (CP) and buffered output enable (OE\) inputs. The device provides 3-state outputs for direct connection to bus-oriented systems. Data at the D inputs is transferred to the Q outputs on the low-to-high transition of the clock pulse. When OE\ is low, the outputs are enabled. If OE\ is high, the outputs are in the high-impedance state, regardless of the clock or data inputs, which allows for flexible bus interfacing.
Each of the eight D flip-flops has a single data input, a clock input, and a Q output. The device is widely used in applications requiring temporary data storage, data transfer, and buffering.
For detailed pin configuration, a datasheet or pin diagram should be consulted.
