Product data sheet Rev. 03 — 21 April 2009 5 of 20 NXP Semiconductors 74LV595 8-bit serial-in/serial-out or parallel-out shift register; 3-state 7. Functional description [1] H = HIGH voltage state; L = LOW voltage state; ↑ = LOW-to-HIGH transition; X = don’t care; NC = no change; Z = high-impedance OFF-state. 8. Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] For DIP16 packages: above 70 °C the value of Ptot derates linearly with 12 mW/K. For SO16 packages: above 70 °C the value of Ptot derates linearly with 8 mW/K. For (T)SSOP16 packages: above 60 °C the value of Ptot derates linearly with 5.5 mW/K. Table 3. Function table[1] Input Output Function SHCP STCP OE MR DS Q7S Qn X X L L X L NC a LOW-state on MR only affects the shift register X ↑ L L X L L empty shift register loaded into storage register X X H L X L Z shift register clear; parallel outputs in high-impedance OFF-state ↑ X L H H Q6S NC logic HIGH-state shifted into shift register stage 0. Contents of all shift register stages shifted through, e.g. previous state of stage 6 (internal Q6S) appears on the serial output (Q7S). X ↑ L H X NC QnS contents of shift register stages (internal QnS) are transferred to the storage register and parallel output stages ↑↑ L H X Q6S QnS contents of shift register shifted through; previous contents of the shift register is transferred to the storage register and the parallel output stages Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V). Symbol Parameter Conditions Min Max Unit VCC supply voltage −0.5 +4.6 V IIK input clamping current VI < −0.5 V or VI > +0.5 V - ±20 mA IOK output clamping current VI < −0.5 V or VI > +0.5 V - ±50 mA IO output current −0.5 V < VO <VCC + 0.5 V - standard driver outputs 25 mA bus driver outputs 35 mA ICC supply current standard driver outputs 50 mA bus driver outputs 70 mA IGND ground current standard driver outputs −50 mA bus driver outputs −70 mA Tstg storage temperature −65 +150 °C Ptot total power dissipation Tamb = −40 °C to +125 °C [2] DIP16 - 750 mW SO16, SSOP16, TSSOP16 - 500 mW |
