TEMP. : 0 to + 70°C; - 40 to + 85°C(V suffix).QDIP-24(Ceramic Bull's Eye)(Ordering Information at the end of the datasheet)PIN CONNECTIONSDESCRIPTIONThe ETC2732 is a high speed 32K UV erasable andelectrically reprogrammable CMOS EPROM, ideallysuited for applications where fast turn-around,pattern experimentation and low power consumptionare important requirements.The ETC2732 is packaged in a 24-pin dual-in-linepackage with transparent lid. The transparent lidallows the user to expose the chip to ultraviolet lightto erase the bit pattern. A new pattern can then bewritten into the device by following the programmingprocedure.This EPROM is fabricated with thereliable, high volume, time proven, p2 CMOS silicongate technology.PIN NAMESAO-A11ADDRESS INPUTS0 0-0 7 DATA OUTPUTSCEOEVppVeeVssCHIP ENABLEOUTPUT ENABLEREAD RV, PROGRAM 25V5VGROUNDA7A6ASA4A3A2A1AO000102vssveeASA9A11OEIVPPJune 19881/10101
