74LVC8T595 Dual supply 8-bit serial-in/serial-out or parallel-out shift register 3-state Rev. 1 9 May 2017 Product data sheet 1 General description The 74LVC8T595 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. Both the shift and storage register have separate clocks. Data is shifted on the positive-going transitions of the SHCP input. The data in the shift register is transferred to the storage register on a positive-going transition of the STCP input. If both clocks are connected together, the shift register is always one clock pulse ahead of the storage register. V and V can be supplied at any voltage between 1.1 V and 5.5 V making the CC(A) CC(B) device suitable for translating between any of the voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). Pins MR, SHCP, STCP, OE, DS and Q7S are referenced to V and pins Qn are referenced to V . CC(A) CC(B) The device is fully specified for partial power-down applications using I . The I OFF OFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when V is at GND level, the Qn CC(A) outputs are in the high-impedance OFF-state. 2 Features and benefits Wide supply voltage range: V : 1.1 V to 5.5 V CC(A) V : 1.1 V to 5.5 V CC(B) High noise immunity Complies with JEDEC standards: JESD8-12A (1.1 V to 1.3 V) JESD8-11A (1.4 V to 1.6 V) JESD8-7 (1.65 V to 1.95 V) JESD8-5 (2.3 V to 2.7 V) JESD8C (3.0 V to 3.6 V) JESD12-6 (4.5 V to 5.5 V) ESD protection: HBM ANSI/ESDA/JEDEC JS-001 Class 3A exceeds 4000V CDM JESD22-C101E exceeds 1000 V Suspend mode Latch-up performance exceeds 100 mA per JESD 78 Class II 24 mA output drive (V = V = 3.0 V) CC(A) CC(B) Inputs accept voltages up to 5.5 V I circuitry provides partial Power-down mode operation OFF Multiple package options Specified from -40 C to +85 C and -40 C to +125 CNexperia 74LVC8T595 Dual supply 8-bit serial-in/serial-out or parallel-out shift register 3-state 3 Ordering information Table 1.Ordering information Type number Package Temperature range Name Description Version 74LVC8T595PW -40 C to +125 C TSSOP20 plastic thin shrink small outline package SOT360-1 20 leads body width 4.4 mm 74LVC8T595BQ -40 C to +125 C DHVQFN20 plastic dual in-line compatible thermal SOT764-1 enhanced very thin quad flat package no leads 20 terminals body 2.5 x 4.5 x 0.85 mm 4 Functional diagram V CC(A) 19 DS 16 17 16 SHCP SHCP STCP 8-STAGE SHIFT REGISTER 14 Q7S 15 MR 2 Q0 3 Q7S 14 Q1 4 Q2 17 STCP 8-BIT STORAGE REGISTER 19 5 DS Q3 6 Q4 7 Q5 18 OE 3-STATE OUTPUTS 8 Q5 V CC(B) 9 Q7 MR OE Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 15 18 2 3 4 5 6 7 8 9 aaa-026283 aaa-026284 Figure 1.Logic symbol Figure 2.Functional diagram 74LVC8T595 All information provided in this document is subject to legal disclaimers.
