SN74LV8153NE4

Shift Registers Overview

The SN74LV8153NE4 is a serial-to-parallel logic converter manufactured by Texas Instruments in a 20-pin PDIP package. It accepts single-wire serial data and outputs 8-bit parallel data. The device operates with VCC1 ranging from 3 V to 5.5 V and VCC2 from 3 V to 13.2 V, supporting an operating temperature range of -40°C to +85°C. It features automatic data-rate detection up to 24 Kbps, eliminating the need for external oscillators. Outputs are configurable as open-collector or push-pull via the OUTSEL pin.

Shift Registers Feature Summary

• Automatic data-rate detection using internal oscillator and counter
• Configurable output structure selectable between open-collector and push-pull modes
• Single-wire serial input compatible with UART format
• Address pins allow multiple devices to share the same bus

Shift Registers Applications

• LED interface requiring high drive current
• Serial-to-parallel data conversion systems
• UART-compatible communication interfaces

Shift Registers Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead-free (NIPDAU) variant listed in the Package Option Addendum. Confirm the package type matches the required N (PDIP) designation rather than PW (TSSOP). Ensure the component status is Active Production before finalizing procurement plans.

Shift Registers Selection Notes

Select this component when designing systems requiring automatic baud rate detection without external timing components. Choose the open-collector mode if driving LEDs or higher voltage loads, utilizing the VCC2 supply rail up to 13.2 V. Use the address pins A0-A2 to daisy-chain multiple converters on a shared serial bus.

Shift Registers Part Context

This part belongs to the SN74LV8153 family of serial-to-parallel logic converters. It is distinct from counters like the SN74LV8154. The NE4 suffix indicates a lead-free PDIP package variant within the broader LV logic series designed for low-voltage applications.

Shift Registers Replacement Considerations

SN74LV8153N is the standard non-E4 PDIP variant. SN74LV8153PWR is the TSSOP tape-and-reel version. Automotive qualified versions include SN74LV8153-Q1.

Shift Registers FAQ

How does the device handle data transmission protocols?

It uses a 2-start-3-address-4-data-1-stop frame format where two consecutive frames transmit 8 bits of data.

What is the function of the SOUT pin?

SOUT outputs a pulse to acknowledge the reception of serial data and is supplied by VCC1.
