SN74HCT595 8-Bit Shift Registers with 3-State Output Registers

1 Features

3 Description

•

LSTTL input logic compatible

– V_IL(max)= 0.8 V, V_IH(min)= 2 V

CMOS input logic compatible

– I_I≤ 1 µA at V_OL, V_OH

The SN74HCT595 device contains an 8-bit, serial-in,

parallel-out shift register that feeds an 8-bit D-type

storage register. The storage register has parallel

3-state outputs. Separate clocks are provided for

both the shift and storage register. The shift register

has a direct overriding clear (SRCLR) input, serial

(SER) input, and a serial output (Q_H') for cascading.

When the output-enable (OE) input is high, the

storage register outputs are in a high-impedance

state. Internal register data and serial output (Q_H') are

not impacted by the operation of the OE input.

•

4.5 V to 5.5 V operation

Supports fanout up to 10 LSTTL loads

Shift register has direct clear

Extended ambient temperature range: –40°C to

+125°C, T_A
