74LS164 8-bit Serial Shift Register

74LS164 8-bit Serial In/Parallel Out Shift Register IC

The 74LS164 is an 8-bit Serial In/Parallel Out Shift Register integrated circuit. It is a component within the 74xxx Series ICs, specifically the Low-Power Schottky TTL (74LSxxx) logic family. This device performs data manipulation and storage in digital applications. Gated serial inputs provide control over incoming data streams. An asynchronous clear function enables reset capabilities. Operation occurs with a fully buffered clock, supporting a maximum frequency of 36MHz. Inputs are diode-clamped to minimize transmission-line effects. This TTL component facilitates serial-to-parallel data conversion.
