technical data IW4042B quad clocked ?d? latch high-voltage silicon-gate cmos ordering information IW4042Bn plastic IW4042Bd soic t a = -55 to 125 c for all packages IW4042B types contain four latch ci rcuits, each strobed by a common clock. complementary buffered output s are available from each circuit. the impedance of the n- and p-channe l output devices is balanced and all outputs are electrically identical. information present at the data input is transferred to outputs q and q during the clock level which is programmed by the polarity input. for polarity = 0 the transfer occurs during the 0 clock level and for polarity = 1 the transfer occurs during the 1 clock level. the outputs follow the data input providing the clock and polarity levels defined above are present. when a clock transition occurs (positive for polarity = 0 and negative for polarty = 1) the information present at the input during the clock transition is retained at the outputs until an opposite clock transition occurs. the IW4042B types are supplied in 16-lead hermetic dual-in-line ceramic packages (d and f suffixes); 16-lead dual-in-lin e plastic package (e suffix), and in chip form (h suffix). ? operating voltage range: 3.0 to 18 v ? maximum input current of 1 a at 18 v over full package- temperature range; 100 na at 18 v and 25 c pin assignment ? noise margin (over full p ackage temperature range): 1.0 v min @ 5.0 v supply 2.0 v min @ 10.0 v supply 2.5 v min @ 15.0 v supply logic diagram pin 16 =v cc pin 8 = gnd function table inputs outputs clock polarity q 0 0 d 1 0 latch 1 1 d 0 1 latch rev. 00
