STMicroelectronics M74HCT138RM13TR 3-to-8 Line Decoder/Demultiplexer
The M74HCT138RM13TR is a high-speed CMOS 3-to-8 line decoder/demultiplexer fabricated by STMicroelectronics, designed to offer the interfacing ability of CMOS with the speed of TTL devices. This integrated circuit is a versatile component, suitable for a wide array of applications, including computer systems, remote control, and data processing systems.
This device features three binary input signals, which it decodes to activate one of the eight mutually exclusive outputs. The decoding function is facilitated by the use of inverted and non-inverted input logic, providing a convenient means to implement hardware address decoding and data routing functions.
The M74HCT138RM13TR operates with a 2V to 6V supply voltage range, making it compatible with various logic levels and allowing it to interface with both TTL and CMOS technologies. Its low power consumption and high noise immunity are consistent with the requirements of modern electronic systems.
The device comes in a compact SOP-16 package, making it ideal for space-constrained applications. The surface-mount package allows for efficient assembly in automated production environments, thereby reducing manufacturing costs and time-to-market for products that incorporate this decoder/demultiplexer.
Key features of the M74HCT138RM13TR include:
- High-speed operation: TPD = 16 ns (typ) at VCC = 4.5V
- Low power consumption: ICC = 4 µA (max) at TA = 25°C
- High noise immunity: VNIH = VNIL = 28% VCC (min)
- Output drive capability: 10 LSTTL loads
- Multiple package options: available in DIP, SO, TSSOP, and SOP packages
With its combination of high-speed performance, low power consumption, and robust noise immunity, the M74HCT138RM13TR is an excellent choice for designers looking to implement efficient decoding and demultiplexing functions in their digital systems. STMicroelectronics' commitment to quality and reliability ensures that this device will perform reliably over a wide range of operating conditions.
