CD4541B Datasheet PDF – Programmable Timer

Part Number : CD4541B

Function : CMOS Programmable Timer, High Voltage Types (20V Rating)

Manufacturers : Texas Instruments

Pinouts :
CD4541B datasheet

Description :

CD4541B programmable timer consists of a 16-stage binary counter, an oscillator that is controlled by external R-C components (2 resistors and a capacitor), an automatic power-on reset circuit, and output control logic. The counter increments on positive-edge clock transitions and can also be reset via the MASTER RESET input.

Function Diagram


1. Low Symmetrical Output Resistance, Typically 100Ω at VDD = 15V
2. Built-In Low-Power RC Oscillator
3. Oscillator Frequency Range : DC to 100kHz
4. External Clock (Applied to Pin 3) can be Used Instead of Oscillator
5. Operates as 2N Frequency Divider or as a Single-Transition Timer
6. Q/Q Select Provides Output Logic Level Flexibility
7. AUTO or MASTER RESET Disables Oscillator During Reset to Reduce Power Dissipation
8. Operates With Very Slow Clock Rise and Fall Times

TPS7A8101DRBR Datasheet PDF – 1A Linear Regulator

Part Number : TPS7A8101DRBR

Function : Low-Noise, Wide-Bandwidth, High PSRR, Low-Dropout 1-A Linear Regulator

Package : DRB 3mm x 3mm Type

Manufacturers : Texas Instruments

Pinouts :
TPS7A8101DRBR datasheet

Description :

The TPS7A8101 low-dropout linear regulator (LDO) offers very good performance in noise and power-supply rejection ratio (PSRR) at the output. This LDO uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance.


1. Low-Dropout 1-A Regulator with Enable

2. Adjustable Output Voltage : 0.8 V to 6 V

3. Overcurrent and Overtemperature Protection

Application Circuit


1. Telecom Infrastructure

2. Audio

3. High-Speed I/F (PLL and VCO)
