The 7432 is a TTL (transistor-transistor logic) digital silicon integrated circuit with four 2-Input OR gates usually in a 14 pin DIP (dual inline package). It operates on a single 5VDC supply. A low input (false) must be an active pulldown below 0.8V, a high input (true) must be above 2.0V while the inputs naturally float above this voltage if not driven unused inputs should be passively pulled up with resistors to reduce noise pickup. A low output (false) will not be above 0.4V, a high output (true) will not be below 2.4V.
The 7432 itself was released in the late 1960s and is currently obsolete and nearly impossible to find, new designs should use the newer equivalent parts 74LS32 (low power schottky TTL), 74HC32 (high speed CMOS), etc. which can also operate at much higher speeds (and some at lower voltages for lower power consumption).
The pinout of the 7432 and its equivalents in the usual 14 pin DIP is:
The 7432 is a quad two input OR gate with TTL levels.
IC 7432 is an "OR GATE"
The 7432 is a Quad Two-Input OR gate. The CMOS version is 4071.

state the differences between PAL and the mixed logic gates, such as the 7400, 7432 ic logic devices?
if you want to use 8*3 encoder than you must the design the circuit according to variable and with the help of k-map and you can not construct the circuit of 8*3 encoder using 7432 (which is or gate ic) only. you need AND gate 7408 and may be NOT 7404 gate according to design.
IC's which starts from 7 are most of them are digital ic's . not all the IC's starts with 7 for example LM380 audio IC CTC810 audio amplifier ic and lm317 voltage regulator ic ,NE555 timer ic, 4017 counter and so other. there are no fact behind them . 7400- nand 7402 -nor 7404-not 7408-and 7432-or 7486-exor 74266-ex-nor 74147 priority encoder.
88 * 7432 = 654,016
7432 ICs are used for summing purposesThe 7432 is a quad dual input OR gate. That means that the device contains four identical two input OR gates. It is often in a 14 pin package, and as each gate has three connections, there are 12 logic pins, a ground pin, and a power supply (5 volts) pin, making a total of 14 pins.Seehttp://html.alldatasheet.com/html-pdf/51073/FAIRCHILD/7432/403/1/7432.htmlFor a datasheet.
Answering "What is differences between pld and mixed logic gatessuch as the 7400 7432 ic logic device name one pld device?"
(+1) 888-448-7432
pld stands for programmable logic device. A 7432 is a fixed logic device, actually 4 instances of a 2 input or gate. A pld can implement the equivalent 7400 series components as required. A popular pld is the 22V10.
