HA13614FH datasheet

Description

This COMBO driver for HDD application consists of sensorless spindle driver and BTL type VCM driver. “PWM soft switching function” for low power dissipation and less commutation acoustic noise at the same time is implemented by using the IPIC- process.

Features

1. PWM soft switching drive
2.  Low thermal resistance: 30°C/W with 4 layer multi glass-epoxy board
3. TTL compatible input level (with 3.3 V logic interface)
4. High precision reference voltage output (for 3.3 V power supply)

Pinout:

components

Functions

1. 16 bit serial port
2. 2.0 A Max/3-phase spindle motor driver with PWM soft switch function
3. 1.5 A Max BTL VCM driver with low crossover distortion
4. PWMDAC for VCM drive current control
5. Power off brake function for spindle motor
6. Auto retract with constant output voltage

SN74LS47 Datasheet – BCD to 7-Segment Decoder / Driver

Posted on by pinout

Part Number: SN74LS47

Function: BCD to 7-Segment Decoder / Driver

Package: DIP, SOIC 16 Pin Type

Manufacturer: ON Semiconductor

Pinouts:

SN74LS47 datasheet

Description

The SN74LS47 are Low Power Schottky BCD to 7-Segment Decoder /Drivers consisting of NAND gates, input buffers and seven AND-OR-INVERT gates. They offer active LOW, high sink current outputs for driving indicators directly. Seven NAND gates and one driver are connected in pairs to make BCD data and its complement available to the seven decoding AND-OR-INVERT gates. The remaining NAND gate and three input buffers provide lamp test, blanking input/ripple-blanking output and ripple-blanking input.

Features

1. Lamp Intensity Modulation Capability (BI/RBO)
2. Open Collector Outputs
3. Lamp Test Provision
4. Leading/Trailing Zero Suppression
5. Input Clamp Diodes Limit High-Speed Termination Effects
