Overview
INTEGRATED CIRCUITS DATA SHEET SAA3004 Remote control transmitter Product specification File under Integrated Circuits, IC02 August 1982 Philips Semiconductors Product specification Remote control transmitter GENERAL DESCRIPTION SAA3004 The SAA3004 transmitter IC is designed for infrared remote control systems.
It has a total of 448 commands which are divided into 7 sub-system groups with 64 commands each.
The sub-system code may be selected by a press button, a slider switch or hard wired.
The SAA3004 generates the pattern for driving the output stage.
These patterns are pulse distance coded.
The pulses are infrared flashes or modulated.
The transmission mode is defined in conjunction with the sub-system address.
Modulated pulses allow receivers with narrow-band preamplifiers for improved noise rejection to be used.
Flashed pulses require a wide-band preamplifier within the receiver.
The SAA3004 has the following features: • Flashed or modulated transmission • 7 sub-system addresses • Up to 64 commands per sub-system address • High-current remote output at VDD = 6 V (−IOH = 40 mA) • Low number of additional components • Key release detection by toggle bits • Very low stand−by current (< 2 µA) • Operational current < 2 mA at 6 V supply • Wide supply voltage range (4 to 11 V) • Ceramic resonator controlled frequency (typ.
450 kHz) • Encapsulation: 20-lead plastic DIL or 20-lead plastic mini-pack (SO-20) PACKAGE OUTLINES SAA3004P: 20-lead DIL; plastic (SOT146); SOT146-1; 1996 December 11.
SAA3004T: 20-lead mini-pack; plastic (SO20; SOT163A); SOT163-1; 1996 December 11.
