SN74LS164 Serial-In Parallel-Out Shift Register The SN74LS164 is a high speed 8-Bit Serial-In Parallel-Out Shift Register. Serial data is entered through a 2-Input AND gate synchronous with the LOW to HIGH transition of the clock. The device features an asynchronous Master Reset which clears the register setting all outputs LOW independent of the clock. It utilizes the Schottky diode clamped process to achieve high speeds and is fully compatible with all ON Semiconductor TTL products. * * * * * * http://onsemi.com LOW POWER SCHOTTKY Typical Shift Frequency of 35 MHz Asynchronous Master Reset Gated Serial Data Input Fully Synchronous Data Transfers Input Clamp Diodes Limit High Speed Termination Effects ESD > 3500 Volts 14 1 PLASTIC N SUFFIX CASE 646 GUARANTEED OPERATING RANGES Symbol VCC Parameter Supply Voltage Min Typ Max Unit 4.75 5.0 5.25 V 0 25 70 C TA Operating Ambient Temperature Range IOH Output Current - High -0.4 mA IOL Output Current - Low 8.0 mA 14 1 SOIC D SUFFIX CASE 751A 14 1 SOEIAJ M SUFFIX CASE 965 ORDERING INFORMATION Device Package Shipping SN74LS164N 14 Pin DIP 2000 Units/Box SN74LS164D SOIC-14 55 Units/Rail SN74LS164DR2 SOIC-14 2500/Tape & Reel SN74LS164M SOEIAJ-14 See Note 1 SN74LS164MEL SOEIAJ-14 See Note 1 1.

A LOW level on the Master Reset (MR) input overrides all other inputs and clears the register asynchronously, forcing all Q outputs LOW. The LS164 is an edge-triggered 8-bit shift register with serial data entry and an output from each of the eight stages. Data is entered serially through one of two inputs (A or B); either of these inputs can be used as an active HIGH Enable for data entry through the other input. An unused input must be tied HIGH, or both inputs connected together.
