UM3750 datasheet

Description :

The UM3750 Encoder / Decoder is a CMOS / LSI digital code Transmitter-Receiver system. Working in the transmit(encoder) mode, the UM3750 will sequentially encode and transmit 12 bits of input. Each of the 12 bits may be 1 or 0 to allow 4096 different codes.

 

Pinouts :

74LS848 Datasheet PDF – 8-Input Priority Encoder – Motorola

Part Number : 74LS848

Function : 8-Input Priority Encoder

Package : DIP, SOP 16 Pin Type

Manufacturers : Motorola ( Freescale )

Pinouts :

74LS848 datasheet

 

Description :

The SN54LS348 / 74LS348 and the SN54348 / SN74848 are eight input priority encoders which provide the 8-line to 3-line function. Theoutputs (A0–A2) and inputs (0– 7) are active low. The active low input whichhas the highest priority (input 7 has the highest) is represented on the outputs(output A0 is the lowest bit). An example would be if inputs 1, 2 and 4 were low, then a binary 4 would be represented on the outputs. The GS (Group Signal) output is active low when any of the inputs are low. It serves to indicate when any of the inputs are active. A0, A1 and A2 are three-state outputs. This allows for up to 64 line expansion without the need for special external circuitry.

Features

1. Low Power Schottky
