TSOP4830 datasheet

 

Description

The TSOP22.., TSOP48.., TSOP24.. and TSOP44.. series are miniaturized IR receiver modules for infrared remote control systems. A PIN diode and a preamplifier are assembled on lead frame, the epoxy package contains an IR filter.

The demodulated output signal can be directly connected to a microprocessor for decoding.

Features

1. Improved immunity against HF and RF noise

2. Low supply current

3. Photo detector and preamplifier in one package

4. Internal filter for PCM frequency

5. Supply voltage: 2.5 V to 5.5 V

6. Improved immunity against optical noise

7. Insensitive to supply voltage ripple and noise

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
