SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 6mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 533 DESCRIPTION The M74HC533 is an high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with silicon gate C2MOS technology. This 8-BIT D-Type latches is controlled by a latch enable input (LE) and output enable input (OE). While the LE input is held at a high level, the Q outputs will follow the data input. When the LE is taken, the Q outputs will be latched at the logic level of D input data. DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC533B1R M74HC533M1R T&R M74HC533RM13TR M74HC533TTR While the OE input is at low level, the eight outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state. The 3-State output configuration and the wide choice of outline make bus organized system simple. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

(Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/8 (per Flip Flop) and the CPD when n pcs of Flip Flop operate, can be gained by the following equation: CPD(TOTAL) = 22 + 16 x n (pF) 5/11 M74HC533 TEST CIRCUIT TEST tPLH, tPHL SWITCH Open tPZL, tPLZ VCC tPZH, tPHZ GND CL = 50pF/150pF or equivalent (includes jig and probe capacitance) R1 = 1KΩ or equivalent RT = ZOUT of pulse generator (typically 50Ω) WAVEFORM 1: LE TO Qn PROPAGATION DELAYS, LE MINIMUM PULSE WIDTH, Dn TO LE SETUP AND HOLD TIMES (f=1MHz; 50% duty cycle) 6/11 M74HC533 WAVEFORM 2: OUTPUT ENABLE AND DISABLE TIMES (f=1MHz; 50% duty cycle) WAVEFORM 3: PROPAGATION DELAY TIMES (f=1MHz; 50% duty cycle) 7/11 M74HC533 Plastic DIP-20 (0.25) MECHANICAL DATA mm. inch DIM.
