SN74LVC138 Dataheet PDF – Decoder / Demultiplexer

Part Number : SN74LVC138

Function : 3-LINE TO 8-LINE DECODERS/DEMULTIPLEXERS

Manufacturers : Texas Instruments

SN74LVC138 datasheet

Description :

The SN74LVC138 devices are designed for highperformance memory-decoding or data-routing
applications requiring very short propagation delay times. In high-performance memory systems, these decoders minimize the effects of system decoding.

When employed with high-speed memories using a fast enable circuit, delay times of these decoders and the enable time of the memory usually are less than the typical access time of the memory. This means that the effective system delay introduced by the decoders is negligible.

Features :

1. Operate From 1.65 V to 3.6 V

2. Inputs Accept Voltages to 5.5 V

3. Max tpd of 5.8 ns at 3.3 V

Applications :

• LED Displays

• Servers

• White Goods

• Power Infrastructure

• Building Automation

• Factory Automation

Description :

BIT1625 is a high performance single chip digital video decoder combining T-CON and OSD. The video decoder interprets commonly used NTSC/PAL/SECAM video content. Signals to the BIT1625 include analog video CVBS and Y/C. The automatic gain control (AGC) function of the analog/digital converter enhances the ability to handle weak and distorted signals. Superior 2D comb filters and advanced CTI processing result in clearer colors and more natural images.

Programmable timing control (TCON) allows the BIT1625 system to use most popular LCD screens. Programmable brightness, contrast, and color saturation, as well as built-in gamma correction, allow users to freely adjust displayed colors. Embedded OSDs make it very easy for system designers to develop easy-to-use user interfaces. The advanced display format controller converts 4:3 displays to 16:9 very smoothly. BIT1625 can be used in a traditional handheld LCD monitor. With its excellent image processing performance, it is also suitable for use in car TV/navigation systems and portable AV systems. [ … ]

General Features :

1. No external memory required

2. Two 10-bit video CMOS Analog-to-Digital Converters (ADCs) in differential CMOS style for best
S/N-performance

3. Fully programmable static gain or automatic gain control (AGC) the selected CVBS or Y/C channel : 0~12db (Analog) and 0~18db (Digital)

4. Automatic Clamp Control (ACC) for CVBS, Y and C

5. On-chip clock generator

6. L-lock system clock frequencies
