Revised January 2004 MM74C164 8-Bit Parallel-Out Serial Shift Register General Description Features The MM74C164 shift registers are a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. These 8-bit shift registers have gated serial inputs and clear. Each register bit is a D-type master/slave flip-flop. A high-level input enables the other input which will then determine the state of the flip-flop. ■ Supply voltage range: Data is serially shifted in and out of the 8-bit register during the positive going transition of clock pulse. Clear is independent of the clock and accomplished by a low level at the clear input. All inputs are protected against electrostatic effects. 3V to 15V ■ Tenth power TTL compatible: drive 2 LPTTL loads ■ High noise immunity: 0.45 VCC (typ.) ■ Low power: 50 nW (typ.) ■ Medium speed operation: 0.8 MHz (typ.) with 10V supply Applications • Data terminals • Instrumentation • Medical electronics • Alarm systems • Industrial electronics • Remote metering • Computers Ordering Code: Order Number Package Number Package Description MM74C164M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow MM74C164N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Connection Diagram Truth Table Serial Inputs A and B Inputs Output tn+1 tn A B QA 1 1 1 0 1 0 1 0 0 0 0 0 Top View © 2004 Fairchild Semiconductor Corporation DS005896 www.fairchildsemi.com MM74C164 8-Bit Parallel-Out Serial Shift Register October 1987 MM74C164 Block Diagram www.fairchildsemi.com 2 MM74C164 Absolute Maximum Ratings(Note 1) Voltage at Any Pin −0.3V to VCC + 0.3V Operating Temperature Range −55°C to +125°C Storage Temperature Range −65°C to +150°C 18V Absolute Maximum VCC Power Dissipation (PD) Dual-In-Line 700 mW Small Outline 500 mW Operating VCC Range Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
