CD4099BPWG4

Latches Overview

The CD4099BPWG4 is a CMOS 8-bit addressable latch from the Texas Instruments 4000B series, housed in a TSSOP-16 package. It operates on a single supply voltage ranging from 3 V to 18 V with a maximum power dissipation of 500 mW. The device features a propagation delay of 400 ns at 5 V, 150 ns at 10 V, and 100 ns at 15 V. Static current consumption is typically 100 μA, while maximum supply current is 80 nA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -4.2 mA. It functions as an 8-channel latch or 1-of-8 demultiplexer with non-inverting polarity.

Latches Feature Summary

• Provides eight individually addressable data latches within a single integrated circuit
• Functions effectively as a one-of-eight demultiplexer for signal routing applications
• Operates reliably across a wide industrial temperature range from -55 °C to +125 °C

Latches Applications

• Data storage in microprocessor-based systems requiring parallel output retention
• Signal multiplexing and demultiplexing in communication interfaces
• Address decoding circuits for peripheral selection in embedded designs

Latches Procurement Notes

Verify the specific suffix 'PWG4' confirms the TSSOP-16 surface-mount package and lead-free compliance. Confirm the manufacturer is Texas Instruments to ensure compatibility with the 4000B logic family specifications. Check RoHS status documentation for environmental compliance requirements before finalizing procurement orders.

Latches Selection Notes

Select this component when a compact surface-mount solution for 8-bit latching is required. The TSSOP-16 package offers space efficiency compared to through-hole alternatives like the PDIP variant. Ensure the design accommodates the specified propagation delays and output drive currents for the target application speed and load conditions.

Latches Part Context

This part belongs to the Texas Instruments CD4000B series of CMOS digital logic devices. The CD4099B variant specifically provides addressable latching functionality. The 'P' indicates the plastic TSSOP package, while 'G4' denotes lead-free and RoHS-compliant manufacturing standards. It serves as a standard building block for sequential logic operations in consumer and industrial electronics.

Latches Replacement Considerations

The CD4099BE (PDIP) and CD4099BNSR (SOIC) are functionally equivalent parts within the same family. Verify pinout compatibility and package dimensions when substituting surface-mount variants for through-hole designs or vice versa.
