ILC555 datasheet pdf

Description

The ILC555 is CMOS RC timers providing significantly improved performance over the standard SE/NE555 and 355 timers, while at the same time being direct replacements for those devices in most applications.  Improved parameters include low supply current, wide operating supply voltage range, low THRESHOLD, TRIGGER and RESET currents, no crowbarring of the supply current during output transitions, higher frequency performance and no requirement to decouple CONTROL VOLTAGE for stable operation.

ILC555 CMOS Timer

Features

1. Exact equivalent in most cases for SE/NE555.
2. Low Supply Current.
3. High speed operation – 500 kHz guaranteed.
4. Wide operation supply voltage range – 2 to 18 volts.
5. Timing from microseconds through hours.
6. Operates in both astable and monostable modes.
7. Adjustable duty cycle.
8. High output source/sink driver can drive TTL/CMOS

Part Number: HA17555PS

Function: Precision Timer

Package: DIP, SOP 8 Pin

Manufacturer: Renesas Electronics

Pinouts:

HA17555PS datasheet

 

Description

The HA17555PS Series are ICs designed for accurate time delays or oscillations. It provides both of trigger terminal and reset terminal in order to enable a wide scope of application including Mono Multi Vibrator and Astable Multi Vibrator, and the number of external components is fewer. Further, it’s compatible with NE555 of singnetics.

Features

1. Mono multi vibrator can be constructed with one resistor and one capacitor.

2. Astable multi vibrator can be constructed with two resistors and one capacitor

3. Delay time can be established widely from several μ seconds to several hours.

4. Pulse Duty can be controlled.

5. The maximum value of both sink current and source current is 200mA.

6. Direct connection of output to TTL is possible.

7. Temperature/delay time ratio is 50 ppm/°C (typ).

8. Output is normally in the on and off states.

Applications:

1. Delay Time Generator (Mono Multi Vibrator)

2. Pulse Generator (Astable Multi Vibrator)

3. Pulse Width Modulator

4. Pulse Location Modulator

5. Miss Pulse Detector
