| TC7MH165FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MH165FK 8-Bit Shift Register (P-In, S-Out) The TC7MH165FK is an advanced high speed CMOS 8-bit parallel/serial-in, serial-out shift register fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation. It consists of parallel-in or serial-in, serial-out 8-bit shift register with a gated clock input. When the SHIFT/ LOAD input is held high, the serial data input is enabled and the eight flip-flops perform serial shifting with each clock pulse. Weight: 0.02 g (typ.) When the SHIFT/ LOAD input is held low, the parallel data is loaded synchronously into the register at positive going transition of the clock pulse. The CK-INH input should be shifted high only when the CK input is held high. An Input protection circuit ensures that 0 to 7 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and on two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. Features * * * * * * * High speed: fmax = 150 MHz (typ.) (VCC = 5 V) Low power dissipation: ICC = 4 A (max) (Ta = 25C) High noise immunity: VNIH = VNIL = 28% VCC (min) Power down protection is provided on all inputs. Balanced propagation delays: tpLH tpHL - Wide operating voltage range: VCC (opr) = 2~5.5 V Pin and function compatible with 74ALS165 000630EBA1 * TOSHIBA is continually working to improve the quality and reliability of its products.
