DM74LS244 Datasheet – Buffer / Line Driver / Line Receiver

Posted on by pinout

Part Number: DM74LS244

Function: Octal 3-STATE Buffer / Line Driver / Line Receiver

Package: DIP 20 Pin, SOP, SOIC 20 Pin Type

Manufacturer: Fairchild Semiconductor

Pinouts:

DM74LS244 datasheet

 

Description

These buffers/line drivers are designed to improve both the performance and PC board density of 3-STATE buffers/drivers employed as memory-address drivers, clock drivers, and bus-oriented transmitters/receivers.

Featuring 400 mV of hysteresis at each low current PNP data line input,
they provide improved noise rejection and high fanout outputs and can be used to drive terminated lines down to 133Ω.

Features

1. 3-STATE outputs drive bus lines directly

2. PNP inputs reduce DC loading on bus lines

3. Hysteresis at data inputs improves noise margins

4. Typical IOL (sink current) 24 mA

5. Typical IOH (source current) : -15 mA

6. Typical propagation delay times
(1) Inverting 10.5 ns
(2) Noninverting 12 ns

7. Typical enable/disable time 18 ns

8. Typical power dissipation (enabled)
(1) Inverting 130 mW
(2) Noninverting 135 mW

VOW3120 PDF – Widebody 2.5 A IGBT and MOSFET Driver

Posted on by pinout

Part Number: VOW3120

Function: Widebody 2.5 A IGBT and MOSFET Driver / Icc= 2.5 mA maximum supply current

Package: DIP, SO 8 Pin Type

Manufacturer: Vishay Semiconductors

Pinouts:

VOW3120 datasheet

 

Description

The VOW3120 consists of an infrared light emitting diode optically coupled to an integrated circuit with a power output stage.

This optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control and inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices.

The voltage and current supplied by this optocoupler makes it ideallysuited for directly driving
IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the VOW3120 can be used to drive a discrete power stage which drives the IGBT gate.
