The 74VHC138TTR from STMicroelectronics is an advanced high-speed CMOS 3-to-8 line decoder (inverting). Fabricated with sub-micron silicon gate technology, it offers high speed with a typical propagation delay of 5.7ns at 5V.
This device features low power dissipation with a maximum supply current of 4µA at 25°C. It has high noise immunity, with VNIH and VNIL at 28% VCC minimum. Power down protection is provided on all inputs, and it can accept 0 to 7V on inputs without regard to the supply voltage, making it suitable for 5V to 3V interfacing.
The decoder function is controlled by three binary select inputs (A, B, C) and three enable inputs (G1, G2A, G2B). If the device is enabled, one of the eight outputs goes low based on the select inputs. If enable input G1 is low or either G2A or G2B is high, the decoding function is inhibited, and all outputs go high. The three enable inputs facilitate cascade connections for memory systems.
Packaged in a 16-TSSOP, the 74VHC138TTR is designed for surface mounting. It operates over a temperature range of -55°C to 125°C and offers 8mA symmetrical output impedance.
