Description

The 74LV164N belongs to 74LV164 family which is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC/HCT164. Data shifts one place to the right on each LOW-to-HIGH transition of the clock (CP) input and enters into Q0, which is the logical AND of the two data inputs (Dsa, Dsb) that existed one set-up time prior to the rising clock edge. A LOW on the master reset (MR) input overrides all other inputs and clears the register asynchronously, forcing all outputs LOW. The 74LV164 is an 8-bit edge-triggered shift register with serial data entry and an output from each of the eight stages. Data is entered serially through one of two inputs (Dsa or Dsb); either input of the 74LV164N can be used as an active HIGH enable for data entry through the other input. Both inputs must be connected together or an unused input must be tied HIGH.

The features of 74LV164N can be summarized as (1)wide operating voltage: 1.0 to 5.5V; (2)optimized for low voltage applications: 1.0 to 3.6V; (3)accepts TTL input levels between VCC = 2.7V and VCC = 3.6V; (4)typical VOLP (output ground bounce) < 0.8V @ VCC = 3.3V, Tamb = 25°C; (5)typical VOHV (output VOH undershoot) > 2V @ VCC = 3.3V, Tamb = 25°C; (6)gated serial data inputs; (7)asynchronous master reset; (8)output capability: standard; (9)ICC category: MSI.

The absolute maximum ratings of the 74LV164N are (1)VCC DC supply voltage: -0.5 to +7.0 V; (2)±IIK DC input diode current(VI < -0.5 or VI > VCC + 0.5V): 20 mA; (3)±IOK DC output diode current(VO < -0.5 or VO > VCC + 0.5V): 50 mA; (4)±IO DC output source or sink current- standard outputs(-0.5V < VO < VCC + 0.5V): 25 mA; (5)±IGND, ±ICC DC VCC or GND current for types with-standard outputs: 50 mA; (6)Tstg storage temperature range of the 74LV164N: -65 to +150 °C; (7)Ptot power dissipation per package for temperature range: 40 to +125°C,plastic DIL above +70°C derate linearly with 12mW/K/plastic mini-pack (SO) above +70°C derate linearly with 8 mW/K/plastic shrink mini-pack (SSOP and TSSOP)above +60°C derate linearly with 5.5 mW/K: 750/500/400mW.(1.Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the 74LV164N at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability. 2.The input and output voltage ratings of the 74LV164N may be exceeded if the input and output current ratings are observed.).
