Product data sheet Rev. 03 — 4 February 2005 5 of 21 Philips Semiconductors 74LV164 8-bit serial-in/parallel-out shift register 7. Functional description 7.1 Function table [1] H = HIGH voltage level; L = LOW voltage level; ↑ = LOW-to-HIGH clock transition; h = HIGH voltage level one set-up time prior to the LOW-to-HIGH CP transition; l = LOW voltage level one set-up time prior to the LOW-to-HIGH CP transition; q = lower case letter indicates the state of referenced input one set-up time prior to the LOW-to-HIGH CP transition. 8. Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] DIP14 package: Ptot derates linearly with 12 mW/K above 70 °C. [3] SO14 package: Ptot derates linearly with 8 mW/K above 70 °C. (T)SSOP14 package: Ptot derates linearly with 5.5 mW/K above 60 °C. DHVQFN14 package: Ptot derates linearly with 4.5 mW/K above 60 °C. Table 4: Function table [1] Operating mode Input Output MR CP DSA DSB Q0 Q1 to Q7 Reset (clear) L X X X L L to L Shift H ↑ l l L q0 to q6 H ↑ l h L q0 to q6 H ↑ h l L q0 to q6 H ↑ h h H q0 to q6 Table 5: Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
