description (continued)

These devices are fabricated using power-saving CMOS technology for high speed and simple interface with

MOS and bipolar circuits. All inputs ( including program data inputs) can be driven by Series 74 TTL circuits

without the use of external pullup resistors. Each output can drive one Series 74 TTL circuit without external

resistors.

The TMS27C010A EPROM is offered in a dual-in-line ceramic package (J suffix) designed for insertion in

mounting hole rows on 15,2-mm (600-mil) centers. The TMS27C010A is also offered with two choices of

temperature ranges, 0

°C to 70°C (JL suffix) and –40°C to 85°C (JE suffix). See Table 1.

The TMS27PC010A OTP PROM is offered in a 32-pin, plastic leaded chip carrier package using 1,25-mm

(50-mil) lead spacing ( FM suffix). The TMS27PC010A is offered with two choices of temperature ranges, 0

°C

to 70

°C (FML suffix) and – 40°C to 85°C (FME suffix). See Table 1.

These EPROMs and OTP PROMs operate from a single 5-V supply ( in the read mode), thus are ideal for use

in microprocessor-based systems. One other 13-V supply is needed for programming. All programming signals

are TTL level. These devices are programmable using the SNAP! Pulse programming algorithm. The SNAP!

seconds. For programming outside the system, existing EPROM programmers can be used. Locations can be

programmed singly, in blocks, or at random.
