SN74LS165 8 Bits Shift Register DIP16

Description

The 74LS165 is an 8-bit parallel-in/serial-out shift register commonly used in digital circuits for expanding input lines or facilitating serial data communication. Below are its key specifications:

Features:

• Parallel Data Loading: Allows simultaneous loading of 8-bit data through individual inputs when the shift/load (SH/LD) control input is low.
• Serial Data Shifting: Shifts data towards the serial output (QH) on each clock pulse when SH/LD is high.
• Gated Clock Inputs: Includes clock (CLK) and clock inhibit (CLK INH) inputs; clocking occurs only when CLK INH is low.
• Complementary Outputs: Provides both true (QH) and complementary (QH’) outputs from the eighth bit.

Electrical Characteristics:

• Supply Voltage (Vcc): 4.75V to 5.25V
• High-Level Input Voltage (VIH): 2.0V (minimum)
• Low-Level Input Voltage (VIL): 0.8V (maximum)
• High-Level Output Voltage (VOH): 2.7V (minimum) at -0.4 mA
• Low-Level Output Voltage (VOL): 0.4V (maximum) at 8 mA
• Maximum Clock Frequency:
  • SN74LS165A: 35 MHz
• Typical Power Dissipation:
  • SN74LS165A: 90 mW

Package : PDIP (N): 16-pin

These features make the 74LS165 suitable for applications requiring parallel-to-serial data conversion, such as expanding microcontroller input ports or interfacing with serial communication protocols.
