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.  
VCC(A) and VCC(B) can be supplied at any voltage between 1.1 V and 5.5 V making the  
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  
VCC(A) and pins Qn are referenced to VCC(B)  
.
The device is fully specified for partial power-down applications using IOFF. The IOFF  
circuitry disables the output, preventing any damaging backflow current through the  
device when it is powered down. In suspend mode when VCC(A) is at GND level, the Qn  
outputs are in the high-impedance OFF-state.  
2 Features and benefits  
Wide supply voltage range:  
VCC(A): 1.1 V to 5.5 V  
VCC(B): 1.1 V to 5.5 V  
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 (VCC(A) = VCC(B) = 3.0 V)  
Inputs accept voltages up to 5.5 V  
IOFF circuitry provides partial Power-down mode operation  
Multiple package options  
Specified from -40 °C to +85 °C and -40 °C to +125 °C
