IC 74HC245 74LS245 3-State Octal Bus Transceiver IC (74245 IC) DIP-20 Package
₹18.99
The 74LS245 octal bus transceivers are designed for asynchronous two-way communication between data buses. The control function implementation minimizes external timing requirements. The device allows data transmission from the A Bus to the B Bus or from the B Bus to the A Bus depending upon the logic level at the direction control (DIR) input. The enable input (G) can be used to disable the device so that the buses are effectively isolated.
Features:-
• Bi-Directional bus transceiver in a high-density 20-pin package
• 3-STATE outputs drive bus lines directly
• PNP inputs reduce DC loading on bus lines
• Hysteresis at bus inputs improve noise margins
• Typical propagation delay times, port-to-port 8 ns
• Typical enable/disable times 17 ns
• IOL (sink current) 24 mA
• IOH (source current) −15 mA

IC 74HC139 74LS139 Dual 2-to-4 line Decoder/Demultiplexer IC (74139 IC) DIP-16 Package
The 74LS139 comprises two separate two-line-to-four line decoders in a single package. The active-low enable input can be used as a data line in demultiplexing applications. All of these decoders/demultiplexers feature fully buffered inputs, presenting only one normalized load to its driving circuit. All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and simplify system design.
These Schottky-clamped circuits are designed to be used in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. In high-performance memory systems these decoders can be used to minimize the effects of system decoding. When used with high-speed memories, the delay times of these decoders are usually less than the typical access time of the memory. This means that the effective system delay introduced by the decoder is negligible.
Features:-
• Designed specifically for high speed: Memory decoders Data transmission systems
• 74LS139 contains two fully independent 2-to-4-line decoders/demultiplexers
• Schottky clamped for high performance
• Typical propagation delay (3 levels of logic) is 21 ns
• Typical power dissipation is 34 mW
